That is very too much for XBO imo.

I agree with the 18,000,000/20,000,000 for Wii U, but i thihnk that XBO will be 30,000,000/35,000,000.

30m lifetime seems way too low. What do you expect X1 to be by January 2016? 

I write my prediction above this comment.

Any way around 18/19 million XBO by January 2016.
