Regarding to lack of the 30e in the US, it could be similar the "let's delay the US launch by a year!" thing that happened to the X5 45e.
The G05 was released and Europe could order the PHEV while the US had to wait a year. I got a really early order slot for the 45e in the US but that was still well over a year and a half after the model had been announced for Europe.
