This announcement was a serious surprise. I never thought I'd see main-title Pokemon games receive a direct sequel like this. I guess the B/W generation of games is the first Generation where they're trying to create a grander plot for the series. The ending of B/W with N was rather open ended after all.
My expectations are that they'll create a whole new region to explore with new main characters, but there won't be any new Pokemon, except for maybe 1 or 2.
It's a very unique direction for the series to take so I'm definitely gonna give one of these versions a try. I'm assuming though since I got White Version, I'm probably gonna have to play White Version 2.
