Well, some of the details were known, but this is taken from the interview at IGN.

On PS2:

On the PS2 side we haven't spared any expense for the online experience. Last year we had a real stable game online out there, but this year it's even that much better. We're going to make it a better experience by getting rid of cheaters and cheese play and have added the ability to use USB voice chat. We'll also have Tournament mode and Messenger to add to the experience.

On the Cube:

The Cube has the Gameboy advance connectivity that's pretty cool. There are actually two levels of connectivity. One, when you just plug your GBA in, and one when you plug in your GBA with Madden GBA in it. This will enable you to unlock exclusive content depending on whether or not you have the cartridge plugged in. There are some hidden teams, special Madden cards, and things like that. We also have this play assist thing on at all times so when the GameCube is connected to the GBA you're getting a lot of extra information on the screen like what plays you should call and things like that.

On the Xbox

But Xbox has some great things, too, as we take advantage of the hard drive, we take advantage of the machine's power and texture memory, and it's just a beautiful game on the Xbox. Out of the three, I think the Xbox version looks the best. We also have soundtrack support on Xbox, so you can rip your own songs and drop those into Madden as well. The Xbox and Cube are also 480P, but not the PS2.
