Microsoft confirms its new next-gen Xbox Series X console will natively support four generations worth of Xbox games when it launches in Holiday 2020. The system will play thousands of games from original Xbox, Xbox 360, Xbox One, and new titles optimized specifically for the Xbox SX.

As it turns out, the Xbox SX was built from the ground up to support last-gen games all the way at the silicon level. Backward compatibility was never off the table and a major feature at the start (MS nor Sony want to displace games libraries and fracture user experiences). Even with the existing Xbox One BC games this task is a massive undertaking of incredibly tough work, but Microsoft's foresight and planning will make bringing older games to the new Zen 2- and Navi-powered behemoth a lot easier.

"It is a new chip architecture. At the same time, we did design the silicon with compatibility in mind, so we did make certain decisions to try to lessen that work," Xbox director of program management told Gamespot.

"But I don't want to trivialize how much work the team's actually doing because there is a tremendous amount of work."

The entire idea of backwards compatibility is "bringing your legacy with you" users jump to the new console. It's not a new ecosystem, just a new console, and all of the games and services are preserved. Microsoft isn't resetting the switch any time soon.

Microsoft has a long history of supporting older systems well past their due date. The Xbox 360 and its library were revitalized thanks to Xbox One's extensive BC support (the same goes for the old-school Xbox) and we shouldn't expect the company to retire the Xbox One family of systems for a long, long time.

Xbox Series X is due out by Holiday 2020. No pricing has been announced.
