More cars, as always. GT does a great job providing many interesting cars, but more is always better.
I would love it if they got all the tracks from the other GT games. I wouldn't mind if they sold some as DLC.
I want an online trade capability, sorta like the PSP version, but with the friend profile capabilities of the PS3 game. I'd especially like it if you could get offers for the cars you leave in your 'shared' section. Not just trades, but money.
Seasonal events should have prize cars for particularly challenging races (with very tight controls on what you can compete with).
