I'm VERY disappointed with Bandai America now. If you need proof that there's going to be no Tamagotchi Music Star World Tour Edition, there it is in front of you (Second post from the top of the thread). The thing that really bugs me is that Bandai even put a press release out for the World Tour, only for it to never see the light of day. We can only hope for a change in plans like there was for Power Rangers - originally after RPM, the only merchandise there that was going to be released were the Super Legends line of collectibles. Recently, Bandai America had a change of heart and is releasing a completely new toyline even after RPM is over. Hopefully this will apply to Tamagotchi as well, because if not, we're done for and will have no choice but to import for any new versions.
On the other hand, as for the color not being released here? They gave a good reason for that, but that doesn't stop other companies like the ones that released those color screen portable Me2 or My Life games. It's depressing that we've gone to this point, hopefully we still see such releases as the new DS game, the TV show, cell phone releases of vintage Tamas like they have for the past few years, etc.
