IMO the only thing that would cause EA to neglect aspects of next yr's version is their work on getting madden ready for next-gen consoles. And if thats the case then you really can't blame them for being more concerned with having Madden prep'd for the launch of next gen consoles moreso than Madden 06.
BTW EA bought Criterion...makers of renderware:

If they apply the
renderware technology (graphics, physics, ai, audio) to Madden 07...watch out. I have a feeling they might tryout some of the next-gen technology with Madden 06...same as VC did with the Triple Pass Rendering techniques they used on nfl2k5 this yr. But who knows. Should be interesting to see what happens.
As for this yr's Madden, Its not a perfect game by any means but IMO its
alot more sim than people give it credit as being. Personally I'm enjoying Madden 05 alot...much more than previous versions.
