Just stopped by the Supercharger spot. It's looking good, but not done yet. Also, I thought I had spotted 4 v.3 chargers, but I now see 16 v.2s... Unless I am missing something, we may not get v.3 here...
Edit: I'm looking at the cable (should be smaller with v.3) and the handle (v.2 has a silver ring around the base, and v.3 is all black at the base). These are all, what appears to be, smaller cable and black ring at the base of the handle. I guess we will find out when it's done.
