Yeah, the way to deal with this is simply to offer a CHAdeMO port. No CHAdeMO = deal breaker for me, I'll rather keep our Leaf. We'll have 31 fast chargers operational over here (Norway) at year-end, next year probably more than twice that. With a 300-mile Model S I could travel all around the country, using only the CHAdeMO chargers (and 16A charging at night). The only other option is 230V 16A sockets which take forever (3.6kW*85% into an empty 90kWh battery equals 30 hours worst case).
I believe the best solution is to offer different charging connectors as options. Make the charging door big enough to fit two connectors (like inside the nose cone) and let people choose themselves what they want. Personally I would order Mennekes+CHAdeMO while US residents might order J1772+CHAdeMO, just J1772, or the combo SAE socket when it's finished.
