Is the xbone going to fall off a cliff?

[starcraft]

Fallout 4 just sold 2 million+ copies on Xbox week 1.

Its likely sold over 4 million copies of Black Ops (in two weeks).

All whilst still selling tonnes of copies of Halo, Rise of the Tomb Raider and plenty of multiplats.

The only reason publishers would even consider forgoing the massive revenue from releasing at low cost on a console with similar power and architecture to the PS4 is a massive insertion of funds from Sony. And Sony is less and less likely to do that, given their strong market position.

So the short answer is no, the Xbox is not about to fall off a cliff.
