2026 seems a bit too early for a new generation when the current one started in 2020 (not counting the Switch's launch in 2017, as Nintendo launched their 9th-gen system in the middle of 8th-gen). Not that this has stopped Microsoft before. The original Xbox was only on the market for 4 years, which is less time than even the standard 5 years for old generations. 7th-gen lasted from 2005 to 2013. 8th-gen lasted from 2013 (well 2012 if you count the Wii U which is more like a 7th-gen system) to 2020. It may very soon be time for the updated/refreshed 9th-gen consoles (PS4 Pro and XB1X came about 3-4 years after the base consoles launched). But 10th-gen starting in 2026? I dunno about that. Maybe 2028.
