I agree the current double cut style is a lot nicer to the throwback they're showing here.
My hope is those are standard level, lower price point bolt on models, and the higher end stuff retains the current look. We're obviously not seeing the whole line.
The one in the video are clearly neck-though designs, but they could be relatively entry-level models. All the current BTBs are neck-though, so perhaps Ibanez sees that feature as key to the BTB line. I agree that I hope the Bass Workshop and premium models maintain the deep cutaways.
