Today Microsoft announced that Xbox Series X will be released this November. Still no pricing, but now we got a launch month. They also haven't talked about the less powerful, all digital Xbox Series S version, but maybe we'll get that information here soon.
Halo Infinite just announced a delay until 2021, so we won't have that to play with this year on the new console, but you'll have plenty of games to choose from as the console will be backwards compatible with every single previous Xbox from Microsoft.
You can expect some improvements to old games as they will be upscaled and have some new HDR rendering options whenever possible.
We're still waiting on a pricing on all the next generation consoles, but now we have a launch month for one of them at least.
