It makes more sense to be with Tencent than with Sony. I don't see why Sony would want these studios. Sony doesn't need studios to make porting, F2P or these type of games, and they typically buy studios who previously did work with them many times. Splash Damage would be a good fit for Micrososft instead.
If Sony wants to buy someone, they should go after Kojipro, Quantic Dream, Remedy, Bluepoint, Housemarque, Ready at Dawn (once Facebook shuts down their gaming division after two or three years), R8Games (to make Wipeout games), or (if possible) From Software.
