They've had a lot of years to test out those prototype parts, though.
The problem was always cost - cost of alloy, cost of molds. Allegedly, that's been solved. If cost is no longer a factor, then they should have stuff ready to go for 2018.
Apologies if this show schedule was already posted. If I know Gamesc, I'm figuring he was the guy that posted it, if posted...he's ALWAYS the guy, haha.
