Dragon Ruby, Haxe (Heaps, OpenFL, ...), Game Maker and I am sure thousands of other smaller engines most never heard of have native console support. The first 2 examples even without huge extra costs.
that's a lot narrower than you think, I wouldn't even put it in the dozens. Maybe a few dozen if we include all the in-house proprietary engines. Being easy to port to console =/= native console support.
But yes, a few dozen out of hundreds of engines is the 99th percentile.
