It all started when Seamus Blackley asked on Twitter if wheelchairs could be an option to Xbox' avatars, and shortly after someone proposed a petition Xbox head Phil Spencer wrote that it's already in the works.
Now Xbox engineering lead Mike Ybarra has published a couple of photos of the new option on Twitter, and in addition to being new the avatars also appear to sport better looking visuals. The next big update for Xbox One is coming later this summer, but we don't know if the wheelchairs are part of it.
Thanks, Gamespot.
