Since the US has not decided on the L3 standard yet, how will this impact the installation of the L3 charge socket?
The best answer I can contribute at this point is 'we don't know'. The TEPCO/CHAdeMO system is UL approved for use - that's a plus - and it's currently the only L3/DC fast charge standard available for the North American market - another plus. How the standards will shake-out if/when the SAE's J1772 committee finishes their connector is anyone's guess. We do know that there will be a vote and a selection for the N.A. market, though. Not likely until end of '10 at the earliest, though.

2) If the line signaling the same, does this mean it is only a matter of the connector itself that changes and does not require a change to the L3 charger port?
I don't personally know the specifics of either the SAE's (not yet complete) signaling system or the finished TEPCO system. However, there were comments made by participants of the last SAE J1772 meeting (Aug '10) that there are enough differences between the two systems that they're not easily compatible.

I personally don't expect any guarantees at this point. It appears Nissan may provide either an installation or upgrade path for a few years once we have a North American standard, but we really don't anything about it other than a Nissan chat comment.

Thanks for any help.
Like many other aspects of this new car, we're going to be in a state of flux until, well, we're not. Hang on and enjoy the ride!
