I bet it will. Why would you bother hampering the design of the charge port door by requiring it to be large enough to cover both J1772 and NACS? The adapter solution is much easier for Tesla and others. And the adapters are cheap.

Yeah, I'm beginning to think you're probably right. Although J1772 is a real standard, NACS is rapidly becoming a de facto "real" standard, and it completely subsumes the purpose of J1772 plus it works for DCFC. NACS is slightly less clunky than J1772 also.

That's basically the same story of how USB BC 1.2 (the old 'battery charging' standard that allowed 5V-1.5A out of USB plugs) came to exist. Vendors were making custom protocols that allowed higher currents than the measly 500mA USB permitted, and eventually the USB-IF threw up their hands and essentially incorporated these industry-made solutions into the USB BC1.2 standard. It wouldn't surprise me if SAE releases some new standard that happens to be NACS...
