I believe it as being and actual prototype.
On the new husky site it talks about it being at the ECIMA show

Although i agree that it does look a little photoshop-ed, there are some details like the welds of the exhaust that are too detailed for a mock-up photo.
That said, it just seems to radical for a new model.
Most new models, being cars, bikes, computers, etc, all carry over a certain amount of architecture from the previous model.
This bike appears to have none.
You would think that something the engine, which has been pretty well defined in its current form, or the new engine, would be something that husky would carry over into any new model.
But to see a new model bike, with new engine, substantially different chassis design, different style graphics/plastics, all seems a bit weird.
Will have to wait and see.
