Harmonix has announced that it will allow customers who've purchased Rock Band, presumably for any platform, to take advantage of its EA warranty program without providing a receipt showing proof of purchase within 60 days, effective June 30th.
In its statement, Harmonix outlined several reasons for its enforcement of its warranty program: "(1) we have a great deal of confidence in our peripherals, (2) we believe we have a great warranty program in place and (3) we found that a large number of the reported problems--especially those after the 60 day period--were due to mistreatment of the equipment."

The loosened restrictions will last until October 1, 2008, when the company will again require customers to report the defects with a receipt within 60-days of purchasing the game. Harmonix stressed that products that have been misused, modded, or broken due to excessive wear and tear will not be covered under the warranty.
