Silent Hill HD Collection. It's intended to resolve frame rate and audio synchronization issues, among other things. The Xbox 360 compilation, meanwhile, won't be patched due to "technical issues and resources."
To recap for those of you following at home: Xbox 360 technical issues cannot be corrected due to technical issues.
Will Konami offer refunds for Xbox 360 owners, or discontinue the sale of the HD Collection for that platform? The publisher has yet to respond to our enquiries, and Amazon shows one copy of the game remains in stock.
Update: Konami tells Joystiq that they will continue to sell the Xbox 360 version of the Silent Hill HD Collection. "Consumers with any questions regarding their purchase" can contact Konami customer support, the publisher told us.
