I'm genuinely convinced that nothing will "save" the Xbox One at this point. There's been so many things we thought would.
Titanfall? Nope
Remove Kinect? Nope
Any game for free? Nope
China? Nope
Halo MCC? Nope
Another price cut? Well... This one had a bigger effect than I expected.
Next up: Halo 5
But regarding the price cut, let's not forget that Sony hasn't dropped the PS4's price at all yet, in any region. Any lost ground from the Xbox One's price cut will instantly be made back up once Sony announces the PS4's first official price cut. And if the Xbox One goes back to $400 in 2015, it will tank HARD. (This is why I think it's more likely that Microsoft will keep the price cut permanent)
The only place where Xbox One stands a chance anymore is the US and UK. Even in these regions, I find it unlikely that it'll overtake the PS4's lifetime sales.
The thing is, Microsoft doesn't give up easily on anything they do. We can expect MS to keep trying with these sorts of deals, for at least another year or two.
