Its a well know name, its profitable and has many fans.
Xbox one X cannot "fail" but they can and will continue to walk in the shadows of Sony and soon Nintendo but thats not a terrible thing.
They will see how sales go and what their fans want if they want to continue the route of pc/console merging they will do this (best for everyone to be honest its very pro consumer)
If there is an indication they need to switch strategy they will proberbly replace Phil and his vision and put someone in charge that goes a more "PS" style route and they will make a different console to counter the PS5
Either way Xbox will be around for a long time and eventually everything will proberbly be streamed anyway and when that time comes I am sure they will keep the Xbox name
