The last Non Rev RIs (2013?) were too massive both as regards body and neck. They felt, played and sounded nothing like a 60ies Non Rev, but very much like a Rev Studio (which essentially they were). Nothing inherently wrong with that, but not what you lot wanted.
If you play a real TB Non Rev, it ironically has a bit of a cheap, flimsy feel - a TB Rev, a Ric or a Fender P feel much more substantial. That is part of its idiosyncratic charm. You can tell it was a rushed design born out of necessity and production cost reduction aims. Will Gibson be brave enough to replicate that "cult" feel for the sake of historical accuracy? The bass would be much neck-heavier for one. Also, it would not really feel like a bass you just paid 1,800 bucks for.
