Ugh, why isn't this on 3DS?
Considering it's claiming to be Black and White 2, I'm kinda expecting a new story, as opposed to the old one but slightly buffed. At the least I want to know what happened to the sages, N and the shadow triad.
It would also be nice if they altered the region to be less linear, perhaps they could give you access to the right side before the elite four and add a whole new area for post game.
I'd really like to find pre5th gen pokemon in the wild, since johto managed with a regional dex of 250, and also we could have more support for using DW abilities during the story.
One thing, I hope they don't mess with the version exclusives. I'm going to get the opposite version to what I've got now, with the expectation I'll get Reshiram and Tornadus.
I'd like a DW expansion, so we can finally find 5th gen pokemon with DW abilities.
However, since it's not on the 3DS (argh) I don't think we'll be getting any major graphical update... Please tell me they're not going to insist on putting the entire 5th gen on DS.
Edit: Also I've got a nasty feeling they're still going to release Grey. Kyurem still looks completely unfinished.
