Uncharted being delayed is fine by me. There will be plenty this fall, and it is a good thing when we have releases spread throughout the year more.
It really feels like Sony is trying to capture the Spring season with their bigger releases. Last year we got Infamous Second Son in the Spring, which was their best "launch" game, and this year we have The Order: 1886 and Bloodborne in the Spring. This isn't new for them either. Killzone became a beginning of the year release on PS3, and even The Last of Us was pushed to the first half of the year. It's really a smarter strategy anyway, as it not only gives the developers more time to polish their games, but it gets them out of the Holiday season slaughter.
