Microsoft said on Friday that it plans to discontinue support for playing original Xbox games on its online service.
"This isn't a decision we made lightly, but after careful consideration, it is clear this will provide the greatest benefit to the Xbox Live community," Whitten said. "And as we look down the road, we'll continue to evolve the service with features and experiences that harness the full power of Xbox 360. To reach our aspiration, we need to make changes to the service that are incompatible with our original Xbox v1 games."
Whitten said Microsoft will be reaching out directly to those affected by the change.
"We'll share more details soon, but in the meantime I want to assure you that the best is yet to come for Xbox Live," he said. "I believe we'll look back on 2010 as a landmark year in gaming and home entertainment, and I couldn't be more excited about what we have in store."
