This game has already been released multiple times on multiple consoles, I don't believe it will sell 700K copies on the 360, let alone the PS3. Anyone who wants to play this game has already played it. That said, it is an amazing game, get it for like $10 at gamestop for the original XBOX, or PC.
While I believe this will be a huge seller on 360, I kept the IPO at 150 DKP because the game will be coming out around the same time as some other great 360 titles, including the shooter Bioshock.
