cisco 890 ISR -vs- 1841 router features

we are trying to get any info on the new Cisco 890 (not 880) series ISR routers.

basically what we are looking for is an ISR router with build in 802.11n, a Docsis 3.0 (not 2.0) HWIC + Avanced IP QOS/VLans + a 100/1000 4 port switch card + Content filtering from trend micro.. the Cisco 881w-Gn-a-k9 + SL-CNFIL-88X-1Y & SL-880-AIS offers this but no HWIC or Doscis 3.0 support or ability to add a simple 4port 100/1000 card. or IPS (AIM-IPS-K9)

the problem with the 1841 it does offer a Docsis2.0 HWIC (hwic-cable-d2 & aim-ips-k9)card, but no content filtering, no 802.11n (802.11G only)and only a 10/100 switch card.. (our ISP is moving to 50mb in 12/08 and 150mb download in 2009) the memory is also very low in the 1800 series -vs- 880 series.

we have found a document on cisco website mentioning the Cisco 890 ISR (file attached search 890 on pdf for details) and we see referances to the 890 replacing the 1800 series (specifically 891w replacing 1811w) and shipping in the next few weeks. (before 12/08)

We want to know if the 890 series will offer 802.11n built in .. an HWIC slot to support the cable card above. +IPS Card..  but are finding limit info searching the web... we hate to make a purchase if a new product is about to be released. we have inquires into our Cisco rep.. and awaitng reply.. any info would be helpful

Although the 890 hasn't yet been released, we can look to the 880 for a few possibilites. Check out the picture I attached that has the 880 on it.
The Cisco 1800 series offers many more features and much better performance than the 800 series routers.
I'm also fairly certain the 890 won't have any HWIC slots... the 800 series is Cisco's fixed-configuration router series. The 1800 series is modular and the 1841 supports HWICs.
As far as the wireless N goes, the 880 offers this as a factory option - so we can guess the 890 will as well. The 1841 will surely support this soon with an HWIC add-on card.
Regarding content security (Trend Micro) this is a feature that is licensed with IOS.
With the 100/1000 card, the lowest router that supports gigabit switch modules is the 7600 series... very expensive. I don't think we can expect to see a gigabit switch module in smaller routers for a very long time. Routers are intended as edge devices now anyways... 10/100 is all that's needed. Now most people use routing switches (like the 3560, 3750, and 6500) for gigabit (core) routing.
As far as IPS goes, IPS is a feature of IOS and as long as you have more 128MB or more RAM and a Adv. Sec. or higher license IPS is handled in IOS without need for an add on card.
I looked in the document you attached and didn't find the word 1811w with a search.
I think it's highly unlikely Cisco will replace an 1800 series device with an 800 series device... historically Cisco just doesn't do that - they always increment the series number when drastically changing a product line or features.
Here's the 1841's data sheet which includes a list of supported modules:

Cheers! Let me know if you have any questions!

so is  performance (throughput) of the router mainly based on memory or CPU?  the 1841 has a max of 384mb/128mb Flash whereas the 880 has 768mb/128mb but I'm unclear if the 880 in fact has a faster CPU being newer then the 1841? or if purchasing an 1841 now would be a risky investment given how long the item has been in service..  another idea is to have an ASA5505 act as the router on the edge for the branch office but I'm not sure it's throughput.

so this begs the question is having an 802.11n Aironet1252 to an 1841 (the AP has a 100/1000 port -vs- 10/100 on the 1841) with a build in Docsis 2.0 HWIC  going to provide faster throughput (both outgoing web, downloads etc.. and incomming SSL /Web WPN -assume no AIM-VPN Card) then  an 881W with integrated 802.11n wirless with a 10/100 wan port to a cisco dpc-3000 (docsis 3.0 cable modem with 100/1000 port) with Comcast 50mb  service (with future 150mb by 2010)

the link below indicates having the router/cable integrated provides better QOS for VOIP.. then having a seperate cable modem via ethernet to a router (See Advanced QOS section - page 5)

in regards to the 890 series.. the existance is confirmed by the PDF from cisco website Attached to this thread.. (search 890)  in terms of the 890 replacing the 1800 series..  intially this was a posting on DSLReports .. but I contacted a Cisco Program Manager who confirmed via phone that the 890's will replace the 1800 fixed configuration models (for example 891w will EOL 1811w) but the modular like 1841 will stay... as far as release/ship dates.. some sources say 12/2008.. whereas more reliable are pushing back to 07/2009 -

This person also said he knew of no plans for an 802.11n or Docsis 3.0 HWIC for 1800/2800/3800 series but it was not his specific area

Performance is mostly based on CPU. RAM is used for caching the image and other OS related tasks.
I have an ASA 5505 (and have setup about 20 ASAs, from the 5505 to the 5520) and have used it as an edge device in the past. It has 150Mb/s cleartext throughput and can easily handle a T3 (although Cisco will recommend higher for a connection like that). As far as crypto throughput goes, it will do about 100MB/s on average. I highly recommend this device. :-)
Having a directly attached line will ALWAYS give you better performance than using a modem.
As far as 802.11n on the 1841, I don't see why they wouldn't release one... (other than the product having been out so long).
Cheers!
