Exchange server 2007 SP2 automatic installation with Microsoft Update?

Hi, I have two installations of Exchange 2007 server SP1  (one with role of Edge, and another with all others Exchange roles), I have in both system (windows 2003 SP2) microsoft update installed and configured with "automatic" updates installation config.
I read the exchange 2007 SP2 will be available in Q3 of 2009, the question is:
When the SP2 will be available, it will be installed automatically by Microsoft update on my systems without any manual confirmation?
Cause this is not a simple update, so I want to plan and install it manually after particoular backups and other operations.
Let me know, thanks

I dont think that SP 2 would be updates\installed Automatically.
So that would be mean that you would have to do manual work.
Exchange service packs have never been pushed out on automatic updates due to their size. You will need to install it manually.

The Exchange 2007 service packs are basically a reinstallation of the entire product, as you can install a fresh Exchange 2007 server from the service pack download. Hence the fact that they are not pushed down by automatic updates - it will be around 400mb in size.
