My picks for FF characters I'd love to see in the next KH game has changed from time to time, but the two constant characters that I've been wanting to see in the next installment would probably be Shadow from six and Rinoa from eight. Given the little tease at the end of the KH2 credits roll with Squall reading a letter and little wings(wings being pretty much Rinoa's motif in eight)floating up from it, It'd be odd if she didn't make an appearance(I dunno, maybe I just wanna see Squall happy instead of constantly frowning all the time). As for Shadow, well that's mostly because he's one of my favorite characters from six, and I dunno, a Sora vs Shadow fight and/or team-up would be awesome.
