2015 will be the year of the PS4
Uncharted 4
Bloodborne
every other first party game that hasn't been revealed yet probably
maybe Final Fantasy XV
Batman Arkham Knight
The Witcher 3
but I think 2016 will save it in Japan
Resident Evil 7
Kingdom Hearts III
FFXV if it doesn't release in 2015
Dragon Quest XI (http://gematsu.com/2014/06/dragon-quest-xi-development-underway)
but they really need some Japanese games now, cause the sales of the PS4 in Japan are less than the PS3 and Wii U
