That article also covered parts of the game for all three major platforms (360, PS2, Xbox), so I would take that with a grain of salt. If you look on the EA page it lists the spring game as one of the features for the current gen platforms, but not for 360, for whatever that's worth.
360 owners, here is what I would brace yourself for: playbooks that aren't as in-depth as current gen, and no spring game. It's my understanding that the 360 will have some new formations (mostly basic sets, different alignments and flexed WR sets - nothing team specific; as well as new defensive formations) and a larger number of formations and plays in each teams' respective playbooks. But, there will not be team-specific formations (Pistol, Emory and Henry, etc) and no trick plays.
I don't know why they are doing this, but it's of no big surprise to me. It takes a lot more effort for EA to create all the graphics, animations, menu screens, game engine, and programming for the 360 from scratch than to update the current gen (since the engine, programming, etc is already there). Not to mention the fact that they totally overhauled the stadiums from the ground up and added a fully polygonal crowd with unique AI. If anyone thought that the 360 version (or PS3 version, if NCAA 07 comes out on it) would be a complete version the first year, they were being delusional. However, you can also look at it this way: next year it should be easy to port over all the enhancements that were made for current gen 07. Look forward to expanded playbooks and all Div I-A stadiums created of 08. Let's also not forget that there are two seperate teams that are responsible for the current gen and next gen version of the game, so while the next gen team had their hands full creating everything from the ground-up for 360, the current gen team had more than enough time to put into creating their playbooks.
This year is the transitional period - current gen has some features that next gen wishes it could have and next gen has some features that current gen wishes it could have. By the time 08 rolls around we will be past the transition period and we'll have the best of both worlds on one platform.
Don't expect the full playbook overhaul and spring game for 360 unless you hear otherwise directly from EA. Sorry for the long-winded post, but it gets annoying to me when some posters (not necessarily from this board) keep stating that certain things will definitely be in the 360 version when all the writing on the wall says it will not.
