Murder Miners is a MonoGame port, which is the way TM is heading. MonoGame is supported on the Xbone, so technically it should be possible. But there's a lot of problems with the scenario. For starters, maintaining 2 different versions of the game concurrently is a huge amount of work for a single programmer. Second, you still have to be accepted into the ID@xbox program. And thirdly, a year from now the Xbone will be the last gen system. Targeting the Xbone now would be a bit of a silly prospect in all honesty. I understand that MS is claiming 100% back compatibility, but they also claimed the power of the cloud was going to revolutionize gaming, and we know how that turned out. So I'll believe it when I see it.
