They're years behind and they have a half baked idea. Of course they're going to come out with one!
They also have piles of metrics saying it's going to become the dominant in the market, that it's way better than the competitors, and that the Xbox interface will be loved by all.
And then it'll come out, be mediocre at best, and silently dropped in 3 years.
It's Microsoft. I've seen this one before
