What Sony needs more than anything else is a solid profit.
Imho, The plan is to take profit from :
- excellent 3rd party sales thanks to good PR, better hardware, packaging, cheap console, indy relationship, easiness of development, better market shares
- not over investing, including on 1st party studio. Better show and get 100 millions $ more profit right now than make studios and launch 2~3 years developments that will not make money for a while. They had only 17 millions $ profit in for the PS division 2014, one more studio would have put them in the red.
- release games on the PS3 the year the PS4 launches because the market is bigger, and the dev cost less. That's GT and TLOU.
The 1st point could lead to more 3rd party exclusives, at last from indies. The 2nd point could change with profit coming and competition increasing pressure. The 3rd point is closed, Polyphony and Naughty Dogs are back in business. Current dev will release. Everything points to a lot better 2015 year.
