Can Nintendo release atleast 1 Wii U exclusive game a month in 2015?

Nope, not gonna happen.
January already looks empty in NA/JP, as Feb will likely be in EU with Kirby delayed to the second half of 2015 there.

We'll see droughts in the first 7 months of the year, then a game a month for the last 5, just like 2013 and 2014.
