I believe both of them are in the same boat as Seabass. Brilliant PS2 games, good PS3 games. From what I know, Seabass doesn't have enough resources and time to fully exploit the PS3. The PS3 as a system was complained about lots by devs as being difficult or complicated to deal with. Couple that with what Seabass said and you'd get the idea. Also, you still can't compare a sports game to another genre. AI much more complex in addition to animations, graphics etc.
I think Sony made a mistake with the PS3, but that's just my personal opinion. Had it been like the PS2, I think we would've seen much better progress from games.
Hopefully, from now on, things only get better. Actually tbh, I don't care much about this gen anymore. I want companies to put next-gen as their primary goal from this moment onwards. Have meetings with both Sony and Microsoft, have a look at their next console, learn how to deal with it asap so we can enjoy almost full potential from day one.
EDIT: What Rad said as well.
