Rock Band 3 was officially announced last week, and with it a batch of new instruments, the two main surprises being the keyboard ($79.99) and the 102 (!) button guitar ($149.99). Added to that are the new cymbals ($39.99) for the drum kit and a MIDI adapter box ($39.99) so you can plug your own keyboard to play the game. We also know that a package including the game and the keyboard will be available at $129.99. It still remains to be seen what the prices will look like in Europe, but it should unfortunately be as usual with a conversion from dollar to euro that will be at our disadvantage. You may want to get ready to get a loan before putting your money down.
