Xbox's Major Nelson has announced there won't be any more Xbox One backwards compatible games until the new year. The team is taking some time off for the holidays, he announced in a tweet, after a big 2017 for the backwards compatibility program.

Microsoft released 136 Xbox 360 games, 7 Xbox One X-enhanced Xbox 360 titles, and 13 original Xbox games for the Xbox One this year. Major Nelson said there will be more releases in the new year, which comes as no surprise as Microsoft has made it clear it's deeply committed to the backwards compatibility program now and into the future. This is especially true for Xbox 360 games; Microsoft has said it won't be releasing classic Xbox games as frequently, with the next ones not expected until Spring 2018.
