I have seen still screenshots of Heavenly Sword in Game Informer and it looks like a fun game to play. As far as Oblivion goes, I have it on the pc and have made over 30 mods for it along with some of the other great ones that were made, and there is no way I could ever go back to the console version. But it is a great game.
Now as far as a ps3 goes, I now have to push my purchase back until the first week of October because A. my car took a crap on me Monday and I had to replace the battery, alternator, and idle control sensor, and B. my previous employer is taking their sweet time with my severance package from when I resigned rather forcibly.
