Since there's a LOT of Yuna cosplayers but not quite so many Tidus cosplayers, I REALLY want someone to cosplay Tidus because of all the lovely photos we'd be able to take. The Moonflow, the ending scene, various other shots--you get the idea.
I'd also like to know if any other X/X-2 cosplayers are going--Lulu, Rikku, Wakka, and maybe even Gunner and Songstress Yuna.
I checked with cosplay.com's forums, and I didn't see any Final Fantasy X/X-2 gatherings. D: But, maybe if you try posting there (A more main sort of cosplay site), then maybe you'd find more luck.
I've only seen a few Tidus cosplays, but on cosplaylab.com, there are quite a few there. :D

I checked Cosplay.com and I still haven't gotten an answer.
Three days till Fanime--I should probably just stop asking and see if I find a Tidus at the con.
I know of a cosplayer who's FANNAME is Tidus, but I don't know if he ever cosplayed his before. :(
Sorry I'm not much help.
