It's current peak year is 2014, if it sold that same amount in 2015,2016 and 2017 it'd finish at almost exactly 20 million. It won't sell that many in 2017 if it's successor is coming out, but I also expect 2015 to be the WiiU's peak not 2014.

I predict 19.3 - 21.5 million sales by the end of it's life.

I'd also expect this year to be the peak.
