FFXV is doing quite well given the amount of time until it releases, its at #35 right now and rising everyday. Could be a big game for the PS4 in the US, exciting, especially because of those awesome previews. Also, I made a comment yesterday that Titanfall on PS4 needs to start moving, and today it is in fact moving, and pretty fast. I think it jumped about 10 places overnight.
Edit: Red Dead 2 PS4 is at #52 and is holding steady, the xbox version is out of the top 100, so RDR2 will be a big game for playstation just like GTA V was
