It's a big year for Xbox, as the company's new console, Project Scorpio, is slated to arrive this holiday season. All Xbox One games will play on the console, and now, Xbox boss Phil Spencer has stressed that it's critical that Microsoft's first-party games be "ready" for the system, presumably for launch."Having our [first-party] games ready for Scorpio is critical," Spencer said on Twitter in response to someone who asked if Scorpio would have any launch games.It's not exactly clear what Spencer means by "ready," though he may be referring to games being updated to support the new power of Project Scorpio.
