Oh good, Gamefreak discovered the rotation effects Nintendo handhelds have had since the GBA. This still looks incredibly dithered and blocky, and while it's a step up from D/P/Pt, I think we can still hold higher expectations for one of Nintendo's flagship franchises--one that makes a ton of money off of its fans--instead of just putting up with incremental improvements every generation.
Imagine, for instance, if the animations in the Pokemon series were on par with those in any of the GBA or DS Castlevania games. It's a fair comparison, I think, because those games use the same scaling and rotation effects as this appears to, and has resulted in absolutely gorgeous results, albeit with a drastically different aesthetic. This, by contrast, is still a bit messy, and I'm hoping it gets cleaned up by release time.
