If the X1 does not pass the Wii U by the end of this year, will you be shocked?

[lucidium]

it depends on the effect MK8 has, if sales just spike and go back to low figures then it will probably overtake wiiu before end of year, if sales maintain then it might be close / not reach that, but it also depends on what games release on the xbox one between now and then, and the hype it generates during E3.

Neither outcome is guranteed.
