The question is if they want or need home console presence at all. A lot of the PS3 games that were steady flowing games that helped PS3 along its way in Japan, got most of their sales (or at least a huge chunk of them in Japan.) The series that appealed to the west too will get the PS4 some sort of recognition (Resi Evil, MGS, FF, KH), but they're essentially viable because western PS4 sales are healthy enough.
All the "mid tier" devs are, as of right now, split between 4 platforms that are much more viable to develop for due to lower costs and higher install base (3DS, Vita, Phones, PS3.) The question is, will the big names of MGS, RE, FF attract these mid-tier devs to PS4? The PS3 was in a very different ecosystem in Japan where alternatives were sparse, but now that handhelds are much more capable and phones are more viable, I really don't think it's a given they'll just jump over. Some of them will, and I think a lot of them very will could, but again it's not something I'd put money on.
Fair enough. I just assumed your "it's over" was in reference to the Wii U vs. PS4 part of quote. Sorry about that.
