I have laid my hands on the new Scubapro backplate, and it's made by Halcyon for Scubapro. Halcyon has very nice system, and the Scubapro backplate is also very nice. However I have not seen the new wings.
Interestingly, I have seen the wings but not the backplates!
The wings look well put together, BUT they use a seemingly completely unique corrugated hose to BCD interface, and that alone puts me off. If the BCD/WIng is actually completely different than any other interface out there, and ScubaPro keeps up its spotty commitment to keeping the line in production, then you might have trouble getting parts for it in the future. Scubapro is good about maintaining parts supplies for its regs, but the parts come at a real premium price.
If you get most any other Wings they fit either the Zeagle shoulder nut (Zeagle, OMS), or the Oceanic shoulder nut (Hollis, DiveRite). In fact the only BCD I have ever had a problem getting a replacement shoulder but piece for is an old X-Tek horseshoe wing, which used a shoulder nut that wasnot a match to either the Zeagle or the Oceanic nut, and I had to replaced the whole bladder pinching assembly on the wing with one that is fully compatible with the Oceanic one.
Since most wings are moving to the permanent attached to the bladder interface, welded/glued into place, and if ScubaPro is uses a non-standard interface, that will be a real problem down the road.
FWIW, ScubaPro has now used at least three different shoulder nut assembly styles in the last 12 years on the tech line. Anytime a company changes design that frequently it also contributes to parts scarcity.
