I think Elon's quote re: the J1772 standard was that it is "crap". So, no, I don't see that happening. I suspect it will be an agreement with some major business(es) to installing chargers on highway locations. E.g. Starbucks, McD, or even outlet mall company.
I remember reading this as well, but we should take note that Tesla Motors is involved with the design and creation of the J1772 Combo Coupler according to the following link. It only makes sense that Tesla would adopt the Combo Coupler that is capable of up to 100kw charges which is better than the Tesla Superchargers 90kw ability. Let us not forget that Tesla Motors will be providing the drive train to Daimler who is on board with the new J1772 standard. Tesla already knows how to implement it into their own vehicles. All the large vehicle manufacturers in North America and Europe have agreed upon this new standard and it only behooves Tesla to get on board. Financially it makes sense in every way and the investors will love it.
Of course this is all just speculation.
