Today's Rock Band for Wii announcement left us with some lingering questions. Here are Harmonix's answers [update: added answers to Mii support, 480p questions]:

Will the Wii version of Rock Band include the Rock Band Store, and downloadable tracks?
When developing Rock Band for the Wii platform, we focused on making the core gameplay experience as solid and enjoyable as possible while tailoring it specifically to the strengths of the platform. The Wii version still contains the robust four-player band experience and all the fun at the core of other versions of Rock Band. However, because the Wii's online capabilities and potential have yet to be fully realized, we wanted to wait before we explored online functionality for Rock Band to ensure that players get the high-quality of online performance they've come to expect.

Will the Wii "bonus songs" be Wii-exclusive, or five songs included on the disc from the Rock Band DLC store?
We'll announce the songs closer to launch. Stay tuned!

Will the Wii version have missing or crippled features similar to the PS2 experience?

Harmonix confirmed today that Rock Band for Wii will be released on June 22nd for $169.99. The so-called "Special Edition" bundle will include the game, drums, microphone and a wireless guitar. Standalone instruments will also be available for purchase on June 22nd. The Wii edition will feature 63 songs, including five unspecified "bonus" songs. We've asked Harmonix to answer some of your more burning questions -- we'll update this post when they do.
