there's a new KOF XIII trailer out, showing all 31 characters in the game (that's a more respectable number of characters for a KOF game by the way) and the new Neomax moves, which use all 3 special bars (kinda like the Ultras in SF4). There also seem to be EX moves (also like in SF4) now, which is cool.
something abour the graphics still seems off to me, I can't explain it. And only 11 backgrounds is a shame. Still looks cool tho.
