Yesterday, the Wii version of Rock Band got a release date (June 22), but some new details have surfaced about the port.
Unfortunately, as we suspected, the 5 bonus tracks are a replacement for DLC, which the Wii version will not have. Also lost in the port is online play.
Also, it's looking likely that Rock Band Wii will not be able to use the Guitar Hero III controller.
Harmonix also hinted that band customization and the Band World Tour mode might not make it in as well.
We're going to assume this is a port of the PS2 version and be upset. That's a lot of cons on an otherwise great game.
