Gimp will never be able to pull a Blender because they are operating on hugely different conditions.

Blender never had to play catch up with a proprietary file format. In Blender's world, fbx and any of the video formats are the way to interop with other studios.

In the Photoshop/Gimp world, the interop format is psd. Under full control of Adobe.

There is also the matter of price. Maya and 3dStudioMax are eye watering expensive, while Photoshop is dirt cheap. As a professional photographer, I can get the 300 GBP it costs me to have Lightroom and Photoshop for one year, in an afternoon.
