I agree, I think that many people will probably praise it for the new graphics, but outside of that, the pokemon look really bad. Some of them look like they are rip offs other pokemon either by themselves or two pokemon crossed over in terms of looks. Then they just get a really random type, although I'm still going to buy it.
Something to note about the "new graphics". So far, and it may be early or I may have missed out on a vid or a pic somewhere, but the graphics of black and white are the exact same as they were for HG/SS. Yes, the game uses a different vantage point for a lot of its overworld, such as the alley ways and walking through a city. However, D/P/Pt and HG/SS all had those same graphics, just all from an overhead vantage point. In fact, you can find a nice Action Replay code on the net that lets you view a lower vantage point in HG/SS. Essentially, the code makes all the towns, buildings, and caves that you go through appear more 3D, just exactly as they appear in Black and White. I checked it out once and it was pretty cool, getting to see that the developers actually designed all the buildings in HG in full 3D.
But back to Black and White, it may look different at first, but notice how none of the pics or vids shown have the character moving in all directions. By now, surely by now, the character model should at least be able to walk in diagonals. You would think, by the way the game looks thus far, that this would be possible. But like I said before, it doesn't appear to be so. It just looks like they changed the view for a few locations, which as previously stated, isn't really a big deal at all seeing as how HG/SS had that ability as well with codes.
All that said, sure, they've made the pokemon move around a bit during battle. Sure, they've changed the vantage point. And yeah, there will probably be more flashy battle effects and such. But thus far, Black and White is honestly no different, graphic-wise, than the previous generation.
