Not bad at all. The issue is keeping momentum, something that the 3DS, Vita and Wii U all screwed up with, despite strong starts (all essentially on par with the PS4). Unfortunately, it looks like it'll be the case here too.
March 19th:
-Natural Doctrine
-Nobunaga's Ambition Online
March 20th:
-Ground Zeroes
April 14th
-FFXIV
The only thing that would likely boost it from that list is Final Fantasy, but that's yet another re-release, so its boost may be negligible.
But Sony has managed to keep the momentum in the west despite a big drought so it's possible.
