Keeping this short and sweet. According to an email sent to me from Fender, with a link to Fender.com, here are the OFFICIAL details of the Rock Band 3 Fender Squier Pro guitar:

$279.99.

Pre-Order begins 1/1/2011.

Available on 3/1/2011.

Discuss.

Note: As some people are mentioning in the comments below, this is probably without the required MIDI Controller.
