I might pick up an Xbox One for Halo. No real major exclusives that blew my mind, but MS really took the wind out of Sonys exclusivity sails by getting KIngdom Hearts and FF XV. People in the west who like Xbox will appreciate it, but the Japanese will ignore it for sure. Kudos to them. Very, very nice.

Why?

It'd only be reasonable for a WiiU version if SE was making it for 360/PS3. But since it's next gen, there's no way it should be for WiiU.

Having said that, making KH3 next-gen is incredibly stupid. Why did they not make even one Kingdom Hearts game for either system this generation? Of all the stupid decisions Square has made, this has to be up there among the top.

It's not exactly Crysis 3 though is it.

No doubt a large number of KH Fans are now on Nintendo systems, because that's where the games have been going lately. And it doesn't look particularly intensive (and there's the fact plenty of other games last gen went to the Wii despite it being far weaker relatively), so I would imagine a Wii U version would sell far better than a Xbone version. 

And yes, it's silly going next-gen. Because if it launches next year you're going to have an install base of around 12mil compared to around 8x that if you include the previous gen (or double that if you include the Wii U).

Though I agree with you on the Wii U argument, I don't think that S-E is going to release KH3 in the next two years. Knowing Nomura and S-E recent record, and the fact that they're working on both FFXV and KH3 simultaneously, I'd expect a 2015 - 2016 window for both games to come out. 

That'll probably give both the PS4/Xbox One a good consolidation time for a rather larger and growing installation base. The same goes for the Wii U as well too.

Out of annoyance that I cannot get this for PS3 and FFXV for PS3, I will buy KH 1.5, FFX HD, and FFXII.

Well, both are running similar hardware with the x86 architecture. The porting should be great this gen, the best porting ever! It's a shame though that the WiiU is oddly excluded from KH3. I really expected it to be for all 3.

Final Fantasy Versus/XV is on Xbox, imagine that...

what the hell square, why not wii u, would sell much better

Correct me if I'm wrong, but the 3 most popular Kingdom Hearts' games are on the PS2 and PSP, not a Nintendo system. Given that the best Kingdom Hearts game on a Nintendo system sold just under 1.9 million units (vs. 4 million+ for the mainline games), it really doesn't make sense that Sony would cater to a lesser fanbase.

Having said that, with KH having sold the best on the PS2, its only reasonable that it comes to XBO, since its in that category of most every other multi-plat that is trying to not heavily downgrade the graphics on a likely poor port.
