It really depends on price cuts, exclusives, etc., but I think at least 10 mil., if not 25-35.

i think that :

360: sells 40 mil life time
ps3 50-60 mil life time
give or take...

i dont think so microsoft have spent to much money on that brand to throw it away

^do you think that will be enough for developers to make games exclusively more on sonys favore

 developers want to make multi-platforms so they can make more $$ - it's as simple as that

What about Sony's in-house development studios and 2nd party affiliates? Just this last year alone, at least 7 1st party games and 5 2nd party games were released for the ps3, all the while games like God of War 2 were being released on the ps2. Once Sony's development teams begin focusing exclusively on the ps3, the exclusives will come.

People always seem to discount SCE Worldwide Studios. Naughty Dog, Team ICO, Incognito, Polyphony Digital, Zipper Interactive, Guerrilla Games, Clap Hanz, Evolution Studios, SCE Japan, SCE Santa Monica, SCE Cambridge, SCE Liverpool, SCE London, etc. are all owned and operated by Sony, and studios like Insomniac, Sucker Punch, Ninja Theory, Media Molecule, Eat Sleep Play, etc. are independent companies that exclusively support Sony platforms.  This leads to a lot of PlayStation exclusives.

oh yeah, it'll easily get some big 2nd party exclusives with the sales it'll have.
