I have a setup almost identical to Mike's in my lab (2651XM, CME 4.x, AIM-CUE) which I used for CCNA:V preparation with no problems what so ever - Honestly, we use CME 4.3 in production environments and with the exception of a few really new non-essential items you can't tell the difference. I believe that they changed the CME version names from 4.x to 7.x only to keep them in line with the full blown CM version numbering = same animal.
