i agree that were going to see a lot of surprises and less mass market oriented games. Many of these once big japanese developers have failed and arent in good situation so i except the likes of square enix, capcom etc coming back to heir roots from their desperation and win hearts mind of gamers again as their prime objective which i think they already starting to do. Also the yen is very low so they have to invest domestically instead outsourcing their franchises which is a good thing if you never liked this practice.
The PS4 is definitely helping this trend with sony funding smaller studios and bloodborne, but also the wiiu brought already so many games by nintendo themselves. I think we are going to see many games selling over 1 million and less over 5 million seller games.
