Making KH 1.5 and 2.5 HD as exclusives makes no sense

[TarHeeLsALLday]

My guess is Sony paid for exclusive rights. It was still dumb of Square to make them PS3 exclusive since KH3 is on both consoles and releasing the HD remakes on 360 would have introduced the series to more people and help sell more copies of KH3 on XB1.
