TexasEV, I did say guess. Just a guess based on years of working with high current electronics. The real value to X owners is much higher, in allowing fast DC charging at the many CHAdeMO chargers out there.
I had not seen the previous $1,000 price tag, but I did know that there was quite a waiting list before. That's the reason that I'm suggesting in this post that people order one now, like I did. As the reality of the 48 amp onboard charger soaks in, the true value of the CHAdeMO adapter will become more apparent.

Well I ordered it. If I get my X by January I need to drive to Harrisburg in February. I was planning to use an HWPC at the Antique Auto Museum, but not at 48Amp. Will use the CHAdeMO that is available near there instead. Hopefully it is working because all the other options will add hours to my trip and the Hilton in Harrisburg has no charging at all in their parking lot.
