Sony have a reputation now, multiplayer and RPGs don't fit into that. I don't think people would trust Sony to put out a game of their usual high quality in those genres and besides we have so many of them from other devs anyway.
Buying more devs who are well known with these genres would work but their current studios should stick with what they're currently doing, its immensley successful.
