Do you mean Black as in Pokemon Black/White or the Pokemon Black that was made up on the internet?
If you mean B/W, then It is coming out next month in Japan and around the same time as HG/SS for everyone else and if you mean the made up Pokemon Black, it'll (hopefully) never be released.
Also, I heard a rumor that they are putting R/B/Y on the DSi Store and Pokemon Stadium on the Wii Store. Does anyone know if this is true and if so, are they still going to do it? I hope they do, purely for the fact that it would be nice to revisit 1st Gen Kanto again as most people can't anymore unless they still have a gameboy.
