New 2012 DC in 2008 forest/domain. Netlogon/Sysvol DFS referrals show only 2012 DC.

I'm in the midst of testing a 2008 to 2012 domain upgrade. I have segmented an existing 2008 DC into a sandbox network, as well as a new 2012 R2 member server. I have added run the necessary ADpreps, and promoted the new 2012 DC into place and all seemingly is working perfectly.
One thing caught my eye though. On the 2008 DC, if I navigate to \\mydomain\netlogon, and check the DFS tab in Windows Explorer, I show the referral list has all DCs in it, including the new 2012 DC. But on the 2012 DC, if I do the same check, this referral list only shows the 2012 DC. None of my 2008 DCs are listed at all.
I have verified by running DFSUtil Cache Referral command and it shows the same results. This occurs for both the Netlogon and Sysvol shares.
Is this normal for a 2012 DC sitting in a 2008 domain or do I have something I need to address before moving forward with an actual domain upgrade?
