Keep in mind that this is likely not supercharger related. Elon confirmed that this is part 3 of the 5 part trilogy. A quick recap on the 5 parts:
1) TSLA Profitable
2) Lease
3) Service
4) Supercharger
5) Right under your nose
On the one hand, he may have just lost track of which is number 3. On the other hand, he likes making a very big public fuss with all his announcements, and the service-side thing so far was fairly low-key.
I'm thinking service too. I can't think of many owners who were thrilled with their service plans.
*edit* jeesh, didn't realize the thread had gone to 6 pages and had already been covered. Ah well, I knew the "loaner" thing couldn't be the full announcement.
*backs slowly out*
