To be honest, the PS4 has been stellar since launch and if it wasn't for MS PR brainwashing, we wouldn't be hearing this "PS4 has no gamez" nonsense. Right now the PS4 has a good amount of games by normal standards, but maybe a little quiet by PlatStation standards. Ok, PlayStation fans may have the right to complain a little because they are used to a high standard but most of the complaining seems to come from "other" fans that probably do not own a PlayStation and never will.
Look I'm not trying to start a fanboy war but we must remember that if Sony studios are a little quiet by their standards, that just means that the slight recession in 1st party games will be counteracted by more games at a later date. Looking at both release schedules for the PS4 and XB1 in 2016, the PS4 edges it with exclusives and I can only see more Sony studios due to release a game soon so if they both do announce more games for 2016, I can only see the PS4 expanding its list more.
In short, the PS4 has more fire power when it comes to first party studios so if it just had a "bad" year, then that just means more games at a later date. Now before we hear people shouting off, the Xbox will get good games but not just as good as PS4. Going by past track records the PS4 will always come out on top when it comes to games, discuss!
