Sony is publishing some pretty cool games this gen, and it does make a nice list on an internet forum -- the problem is none of these games are hits and none of them move any hardware. Killzone 2 has dropped down the sales charts like a rock, being outsold in the most recent April NPD by the almost two year old Halo 3.
The first Uncharted basically went uncharted on the sales charts. LittleBigPlanet was little alright -- in its impact sales wise. Ratchet & Clank on the PS3 never cracked the top 10 of the NPD charts either (not even close). Resistance 2 was no where close to Gears of War 2 sales wise.
I'm gonna go out on a limb and say inFamous is also going to perform similarly to the above mentioned games -- lukewarm software sales ... zero impact on hardware.
FFXIII is on the 360 in the West and not even coming out at all in the West until 2010 anyway, on top of the fact that recently Square-Enix's president has been dropping not-so-subtle hints that the game may not come out even in Japan this year.
