MTV has announced that the wait is over for Wii owners: its successful game Rock Band will hit Nintendo's console June 22. The price is the same as for the versions for the other consoles, $170. In addition, extra instruments will be available, which means that Wii gamers will be able to buy a second guitar at retail and put a full band together instantly.

"The Wii's success among casual and core gamers of all ages makes it an ideal match for the cross-generational appeal of the music featured in Rock Band," says Bob Picunko, Vice President of Electronic Games and Interactive Products at MTV.

Also exclusive for the Wii version, there are five extra songs on disc. Also, the instruments don't use the Wiimote, as they work much like they do on other consoles. However, there's currently no word on whether Rock Band for the Wii support downloadable content or online play, but I guess it eventually will.

Rock Band, the game released by MTV and Harmonix, has recently reached the six million downloads mark. Also, Harmonix has released a major patch and a full-featured, in-game music store. The store has a "user-friendly interface to streamline and enhance the music shopping experience," and allows players to "view, purchase, and sort all downloadable songs tracks by Artist, Song Title, Genre, Albums, Pack," with full album art, song previews, and instrument-by-instrument difficulty levels.

Rock Band is a party game that was released bundled with controllers shaped like guitar, drum set and microphone. The full package costs $170 and it seems the price doesn’t represent a problem among the music-themed video games fans.

The game includes 58 playable songs such as the Rolling Stones' Gimme Shelter and Metallica's Enter Sandman and it was already released for Xbox 360, PS2 and PS3. More tunes can be downloaded over the PlayStation Network and Xbox Live for prices varying from 99 cents to $2.99.
