Handhelds are weird.
Years after the 4DS is on sale and Sony have left the handheld market people will remember the day that one niche RPG sold a couple of thousand more.
We only bring up Conception because there's few PSV/3DS multiplats in general. The ones we do have either heavily favour Vita, or just narrowly favour 3DS. In general, these games sold low amounts combined:
PSV : Conception II: Children of the Seven Stars ( Spike Chunsoft ) { 2013-08-22 } - 19,815 / 34,277
3DS : Conception II: Children of the Seven Stars ( Spike Chunsoft ) { 2013-08-22 } - 5,432 / 12,000
There's also this thing:
PSV : Exstetra ( FuRyu ) { 2013-11-07 } - 11,607 / 11,607
3DS : Exstetra ( FuRyu ) { 2013-11-07 } - 3,173 / 3,173
3DS : Zero Escape: Virtue's Last Reward ( Chunsoft ) { 2012-02-16 } - 7,890 / 17,913
PSV : Zero Escape: Virtue's Last Reward ( Chunsoft ) { 2012-02-16 } - 6,133 / 15,454
3DS : Time Travelers ( Level 5 ) { 2012-07-12 } - 9,761 / 22,162
PSV : Time Travelers ( Level 5 ) { 2012-07-12 } - 9,887 / 21,000
PSP : Time Travelers ( Level 5 ) { 2012-07-19 } - - / 11,267
The 3DS "winners" all came out while Vita was 10 feet under too. Maybe the splits would be different today?
how much does the KH games sell in japan? I wonder with these numbers if KHIII being ported to the wii u is being considered.
I'm not convinced Wii U will be around by the time KH3 comes out. We're not seeing that game anytime soon. But since you asked:

normally i would say the same thing, but if the PS4 continues to track like it is, and the game sells mostly in japan, you never know. have there been any ps4 3rd party games that didnt meet the same fate as 3rd party wii u games in japan? I dont recall any big selling ps4 games either.
Outside of Birth By Sleep, the majority of sales for Kingdom Hearts games come from the west.
