I'll go with yes, but after 2016.
This community grows, but not very fast. Growth has accelerated slightly over the past year or so, but it's also true, in my opinion, that the year and a half or so between mid 2012 and the end of 2013 (the KO3) is "Peak Kong." Right now is the culmination of what King of Kong started. I don't see DK getting bigger from here though. The game is very close to being "maxed out", on several levels.
To get 40-50 new kill screeners between now and the end of 2016 would require more than one per month. At the rate things have been going, it might actually be close, but I'm still gonna go with later than 2016. Maybe significantly later than 2016, if interest tapers off.
(This of course assumes that there won't be some new, unexpected development that comes along and makes a bunch of people suddenly want to take up DK, but I can't imagine what that would be.)
