The Kingdom Hearts franchise is scattered among several consoles: ps2, GBA, psp, DS and 3DS. Because of that, it's probable that only some diehard fans have played all the games in the franchise. With that in mind, it makes complete sense to develop two HD collections, featuring 6 out of 7 games in the franchise. What makes piss poor sense is to make said collections exclusive to one platform. it's completely counter productive to the basic idea of allowing several people who couldn't play all the titles to do so. it's even a great option to bring new fans but the potential get's wasted.

The correct move would be releasing 1.5 and 2.5 on both Wii U, xbox 360 and ps3, allowing the biggest possible audience to play those six games and get ready for Kingdom Hearts 3.

OK EVERYONE THIS IS WHERE IT BEGINS.
TIME TO RALLY TOGETHER FOR KH 1.5 & 2.5 HD COLLECTIONS ON VITA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
WHO'S WITH ME??

I suspect that at the time, Square Enix and Sony signed some sort of contracts regarding KH1, KH2, FFX, etc. to keep them exclusive to Playstation. That's my take on it.

We are talking about SE... everthing what they do makes no sense...

WiiU and PS ? Yup, that would make sense.

But 360 ? Just check the sales of any Japanese game on the console, including JRPGs.

i think this is the first time i've ever agreed with you...


...especially when we already know that kh3 is multiplat for ps4 and xbone.

Of the four games featured in the collections, all four were on Sony platforms (I know Chain of Memories was on GBA first, but the PS2 version was different). I'm guessing it's easier to port and upgrade the games to the PS3 than other systems, or maybe Sony just signed a deal to keep them exclusive.

Sony payed for exclusivity. What's the big deal?

bold: I know, but if they're gonna bother with KH 3 on Xone, it doesn't make sense to warm the fanbase with those collections.
