I have a feeling we may see another similar blue (like the Kinetic Blue on the Hot Wheels edition or a blue like the Laguna blue on the new Corvette) even before the 5th gen makes it last go round.
As for Aqua Blue, as much as I love mine, I think its gone for good.
I'd be more than happy if they never made another medium blue for the 5th gen (since I like having a rare color lol) but on the other hand I really feel releasing Kinetic Blue model wide instead of just a special edition would have been the way to go. I wouldn't be surprised to see Chevy release it on all models next year just like the Synergy Green....pissing off the current Hot Wheels owners/buyers.
Now if there is no 5th gen medium blue again, but a nice medium blue on the 6th....Wow will that ever make it even more temping to move on up lol.
5th gen IS SOLD! 6th gen built 10/14!!! Can't wait!!
