I agree with you about the titles, I was always more for the color generations! Haha.
You are completely right in the way you think. The graphics from HG/SS were nice, and now they have these new, completely 3-D graphics, like they're trying to improve something that was already great. I wonder if the games that will follow this new one will keep the 3-D. Probably.... With the 3DS and all. And it's true, from what there is to see so far, it looks much too realistic for Pokemon. It reminds me of those Gamecube Pokemon games like Colosseum and XD. Sort of dark, too. I hope the whole game won't be that way. We'll just have to wait and find out.
