Back when I was the Editor of Official Nintendo Magazine, I had a meeting with Nintendo to talk about their upcoming releases. At the time Mario Galaxy 2, Metroid: Other M and Skyward Sword hadn't come out yet. I mentioned how excited I was about 'the big three'. The guys at Nintendo said 'what about Pokemon?' I said, 'what about it?' For some weird reason I never really 'got' that Pokemon was a big deal. But it is! So while I, personally, don't care too much about Pokemon Black/White Version 2, and when it's going to come out. I know some of you guys/girls do!
So yeah, October 11 is the date. Pokemon White/Black Version 2 is a DS game, but the 3DS does have backwards compatibility, so you will be able to play on your 3DS.
So yeah, it may not be for me -- I was just that little bit too old when Pokemon was popular -- but good luck to all those who love it!
