Dont they already own most of these at least in part?
I was sure they bought Media Molecule already!

Insomniac Games or Sucker Punch, they have been working with Sony for way too long for Sony not to snatch em up first.

Insomniac Games seems the safest bet.

MM has only one game
Quantic Dream only showcases one game too on the PS3
Sucker Punch has to confirm with Infamous 2
thatgamecompany is nice for PSN but not really a big fish
UFG is currently also only one game.

I don't see why they are going to buy any more studios. They have contractual agreements with these studios, and they all seem quite happy working with Sony

I chose Gamecompany but I think almost all of them are possible in a way.

I was sure they had something going on LoL!

But i can see them definately buying more shares!

Media Molecule, probably because it would be the cheapest as well since they only have one IP that they ever worked on and I beleive they are a smaller firm. Plus they are the developer who brought us the Play. Create. Share. genre on the PS3. Insomniac and Sucker Punch could cost Sony alot of money to bring on permanantly being bigger firms.

I think Media Molecule is the most likely one to be bought. But whether Sony decide to do some shopping at generation's end, is a whole other discussion

media M. would be my bet..hey they were the one's who brought ragdoll kung-fu which was a great game. and with now little big planet they are on a roll.

media molecule would be my guess. Both Insomniac and Sucker Punch have mentioned several times that they like to be independent but still have a relationship with sony.
