The price discrepancy could go back to the issue from last year regarding Red Octane and their attempt to get a wireless guitar on the Xbox 360. Turns out to license Microsoft's proprietary wireless technology would have increased the cost of the wireless guitar and the company decided not to do it. Could $20 be the magic number being tacked on for the consumer? This would also assume, if the pricing is correct, that neither the drum set nor the microphone would be wireless given the lack of a price difference between the two systems. Although, we do have a statement regarding the price discrepancy as well. We were told by the Harmonix rep, "I am not aware of a price discrepancy." It looks like it's going to be a while before the actual, solid, final price of the peripherals gets nailed down. Right now, it's still all rumor and speculation -- officially.
