I think Resistance Remake will be there from Insomniac.
I would love a Snatcher Remake from Kojima although it is borderline impossible.
I think I might be in the minority here, but I'd prefer a KZ remake than a new Socom. Socom wouldn't survive against COD and BF. But then again, a new MAG would make an amazing GAAS game. That game was way ahead of its time.
Sony needs their own beat'em up and Karting game as they lack in the arcade racer department.
I would love Capcom to make a new PSABR in the essence of Power Stone.
And partner with Sega and MM to make am Astrobot Karting with the LBP / Dreams creation tools.
They also need to release Dreams for PC. That game could be huge on PC.
Finally I think we will get news on new tiers or something for PS+ / PSNow with the Crunchyroll merger being complete.
