Rumor: Second generation Xbox One has been in production since February
Earlier this month an FCC filing revealed that Microsoft had plans for a new model of the Xbox One. Details on the new version of the Xbox One have been scarce, though the filing did specify that the console would feature a new wi-fi chip.
According to an image post on Weibo from user Microsoft信仰中心 (via NeoGaf) the new Xbox One has been in production since February 2016. In addition to the console having been in production, the user detailed that there would be a white version of the new console whose production name appears to translate to Xbox One second generation.
Looking at the image (above) it appears as though the second generation was planned since 2014, a year after the Xbox One released. The weight, 600 ~ 800g (roughly 1lb+/-) , seems a bit odd considering the that the Xbox One is currently 7lb. If the second generation is truly that light, it could be the rumored "lightweight" digital only Xbox One.
Apparently, once entering production the second generation Xbox One was planned to have plan of manufacturing 400,000 consoles per week.
Microsoft has not verified this rumor. The FCC filing suggests that the console will be revealed this Summer.
