The Official Xbox Magazine podcast has an interview in their latest episode with Alex Rigopolous where he talks about Rock Band details. He says the big bundle (drums, mic, guitar, game) PS3 version will include wireless guitar controllers while the 360 version has wired ones because the cost of Microsoft’s wireless technology would make the bundle too pricey. To get around the 360’s USB port limitation, the Xbox version will include a hub.
Also the final track in solo career mode for the drums is The Who’s “Won’t Get Fooled Again” and the band career mode isn’t linear like solo career, but has you building your fan base by playing cities and re-visiting them to maintain your support. There are also some cool things mentioned like risk-versus-reward challenges at venues and indications that Rock Band controllers should work with Guitar Hero games. Check it out, it’s a good listen.
