The demo confirmed that they've basically made the same improvements to the gameplay that NCAA did this year. I'm glad that they ditched the "Pre-order to the Full Demo!" crap and offered a good five minute, four quarter demo this year. Most of my interest is in seeing how improved the franchise and career modes are over last year's game, especially the terrible career mode.
The main issue I have is that they redesign their HUD every year and that score bar seems to be moved around for no reason. It should be at the bottom of the screen so that it gives you full view of the field. but having this bar in the top left corner makes no sense. I'd love for them to just throw all of that crap out and sign deals with NBC, CBS, Fox, NFL Network, and ESPN to use all of their assets to make each game look like they do on TV depending on what channel the games are schedule to air on. The NCAA team already does this with the ESPN integration into the presentation and the last NCAA Basketball game from EA featured the presentation and commentators of both CBS and ESPN, so there's plenty of precedent for that to happen.
It's odd that the Madden and NCAA teams seem to work together on the engine/gameplay improvements while everything else feels like they're on opposite sides of the country.
