Got the PS3 version today at TRU. Some observations after 3-4 hours of play:
-it is not blurry. May not be as sharp as 360 in some areas, but it's not blurry.
-it does not chug. The first minute of the clocktower, there is some minor slowdown, other than that, the gameplay sequences run like butter. Cutscenes are definitely choppy, but I'll only watch these once or twice, then skip them forever (or in the case of MGS4, some of the cutscenes, I couldn't even make it through of the first time).
-load times are annoying. Very annoying.
-IGN was paid off by MS. Those little shits
So, don't be scared of the PS3 version. Would I have liked an exact port of the 360? I'd be crazy not to say yes. Given that the perfect port does not exist, I would have to buy a 360 to experience the game in all it's glory, but my cousin is on his 5th 360, so all and all, I don't feel so bad about Sega's fuckup.
