+We made a preliminary port of GIMP to GTK+3 a few years ago and intend to complete it once v2.10 is out. 
GTK+3 based GIMP will be eventually released as v3.0 (see the [roadmap](http://wiki.gimp.org/wiki/Roadmap)

can live with GTK+2 based GIMP another year or so. However not providing high bit depth precision for editing 
makes GIMP unusable in professional workflows involving color grading and retouching.

GIMP's architecture cleaner and prepare it for non-destructive editing (a feature currently planned for v3.2).
