I do think they need more big studios. Having closed so many recently was definitly the wrong choice.
Sony does need more big franchises. On that front they have always been weak and have dropped established ones way too easily.
They can't depend so much on Naughty Dog and Guerrila alone. Even Santa monica has been slow with their output. Media molecule is basically an indie dev and Sony Japan is all over the place.
If they managed to foster 2 more studios like ND and Guerrila, they would be in a much better place. This also taking into account that Naughty Dog lost its ability to have 2 teams working at the same time so they are not as dependable as before. After Uncharted 4 we wont hear anything from them for another 2 years.
Sony needs studios especially for those off years.
