It was eventually bound to happen. EA has announced that their Rockband franchise will be coming to the
Wii in the near future. All that we are left with is a "coming soon", but you can probably expect it some time this year.
So far no screens or other details have been announced, but we will surely keep you updated. Rockband was created by Harmonix Music Systems, also known for their work on Guitar Hero.
