SAE agrees on J1772 Standard Charging Plug for PHEVs and EVs

It is a japanese thing. The europeans and americans agreed to this frankenplug. Toyota has not said it has any intention to put chademo on any car, they simply have joined the japanese consortium.

Part of the problem with the "standard" was it wasn't a standard it was a closed for pay plug and socket system. If you weren't japanese you got screwed, and with the nuclear disaster, tepco left its leadership role, and turned it over to a guy from nissan.

With chademo almost certainly about to die overseas, the japanese government tried to say it.

That would have certainly helped a year ago, but the foot dragging and licensing fees may have killed this for all but a few hundred charging stations in north america.

Why would manufacturers mutiny. They can implement the frankenplug less expensively than J1772 + chademo, and it has more capabilities. Only reason to support chademo is if there is more of a installed base of charging stations, which in the US is pretty sparse. If those stations add frankenplug, then no reason at all. Some charging stations may support both, but no reason for a car company to add it now in North America. Tesla can easily provide an adapter to frankenplug as their charger already has the high voltage dc pins and green phy communications.
