Well I don't think there's any question about it, PD, in terms of productivity, has been God awful dating back post GT3 imho. They've just built up a big enough franchise that it hasn't really mattered. Same with CoD and Activision.
It's very disappointing that Sony killed a studio like Evolution, but let's PD do whatever they want basically.
edit, this was a reply to Azz, mobile sucks.
