This seems all too common for EAs first sports titles on a platform (i.e. their first Madden, NHL, FIFA, etc.), especially if the game launches close to the hardware (not the case here but whatever).
So much so that I find myself avoiding their first efforts on a new machine.
My guess (and it's a total guess) is that they rush it out by porting it from somewhere else for year 1 just to get it out there. By year 2 they've been developing it properly on the platform in question so you get a better game.
Case in point was the first NHL game way back for PS2. It resembled the Vita Madden, in that it was decent but glitchy. NHL 2002 blew it away in terms of quality. I expect next year's Madden to follow the same pattern, assuming they stick with the Vita.
