That said, I think I'll respond to some of the posts that aren't sure about Kanto being in the game. In general, you break G/S if you don't have Kanto included in the game, because it expands into a kind of sub-story and gives you more to do than the average Pokemon game of present times. The multi-Region travel is one of the primary things that has made me want a G/S Remake for so long, so I really hope they don't scrap Kanto and ruin a large part of this remake for me, at least.
Maybe the Sevii Islands will make a return? Well, the Japanese release is coming out in the Fall, so I guess we've got plenty of time to wonder about it... XD
There is a lot I'm looking forward to from this game, but mostly to get back into using all my Generation II Pokemon again. I've really missed Johto.
