I've popped enough ProCore tubes (including this weekend apparently - figured it out this AM on my commute) that in my mind the gen-2 would find a way to beef up the tube or possibly combine the inner and out into one unit one wall instead of two but that wall would be much thicker.  That said, the current system is really just a trainer-tire with a hole in it and an inner tube with a fancy valve, so the investment involved in improving the system would probably vastly exceed the initial product (minus marketing costs).  I've had good results with ProCore with wider rims/tires in SOME situations - namely when the rim has a relatively short sidewall. Certainly, with my i39 Velocity rims a number of dents have been prevented by running ProCore.
