Did you see how crappy the DP beta images were? They looked like fanmade sprites.The pictures of the battle scenes look absolutely awful!
If you look here: http://serebii.net/blackwhite/pics.shtml
The pictures labeled "Zorua vs Zoroark" (under the 5/13 date) show not only ugly platforms that the Pokemon are standing on, but the sprites themselves look pixely, and horribly shaded. I'm praying that this is shot is prototypical and that there will be more development.
Also, there seems to be two different battle scenes; one with the 3-d settings where the entire Pokemon are both visible, and one with the standard setting we have come to know. Why are there two settings, and do we know what circumstances under which they are used?
Give em time, they're probably still inventing new pokemon.
