Hopefully, (I hope) that they'll be brand new sprites with brand new pallettes, the sprites will still be in the same pose as the original ones, and the sprite will be animated, just like the Crystal sprites.
The trainers...they should look good, either way.
Overworld sprites, I don't really care about. Probably will be a mix between Platinum and D/P.
And the battle scenes, well I don't think they'll be too good. :(
