Time was never "in" for Xbox One.
It was never, ever, under any circumstance going to be WW leader in console sales. The brand is simply too catered and rooted for the American market to be a legitimate WW player.
If one was to drastically change the brand to actually be able to compete WW, it would cease to be the very console that Xbox fans love and enjoy.
Titanfall fits perfectly, its a competitive online shooter with gritty graphics. The game at times look like Michael Bay's turd of a trilogy called Transformers. The next big games to carry the console will be Halo, and possibly Gears, more of the same, for the same market, for the same demographic.
It will somewhat work in US and slightly less in Europe, but thats it, they are not leading anything, ever. Unless they completely re brand the whole thing, and they wont.
