It looks like Harmonix and Mad Catz have come up with a unique solution to not releasing a new Rock Band game this upcoming Holiday season as they will be re-releasing
Rock Band 3 bundles with instruments.
Posted on the Harmonix Forums page, the agreement appears to be bringing bundles of the game with either the wireless keyboard, Wireless Fender Stratocaster Guitar Controller and/or the Wireless Fender Mustang PRO-Guitar Controller.
It does not really indicate as of yet whether there will be three individual bundles, or if this will be all three controllers and the game in one bundle. With the price of RB3 recently dropping to $19.99, I am leaning toward the latter as all three of those peripherals were extremely hard to come by last Holiday season and are still difficult to find in stores today. Hopefully more info on the bundles, including pricing and availability, will be released soon
