Well NBA Live and MM were both the first time the EA basketball teams worked with the PS3. NHL and NCAA were a first as well.
Some gaming companies are calling EA out on being lazy and I kind of agree. But I wouldn't worry too much though, I would be really suprised if next year EA games continued to have these problems. Madden this year took a lot of heat for the 30/60 FPS issue.
One good thing though is the recent Burnout game made by EA was made on the PS3 and ported over to the 360. Both got very good reviews.
