It's almost certainly fake. The original poster (" sneakypeekyeeky ") on Reddit first posted the same dial (in terms of maneuvers and colors) in a poorly photoshopped form. Then, someone commented on his post telling him where to find a tool that makes more realistic-looking dials. sneakypeekyeeky then posted the link you see at the top of this thread.
Well that seems like rather convincing evidence that it is not legit. Which gives hope for something better.
Still, it's pretty funny how the reaction to the dial differs from Imperial and rebel players. Come join the Empire! Our ships don't handle like a rusted out jalopy rattling down the freeway at 70 mph.
