Elon Musk on Twitter
I think though pick-up has higher resource priority than Semi, Semi might come to marker sooner than pick-up (and even Y), because of the difference of initial volumes.
I was really surprised and delighted to see this "mini-announcement burst." Elon clearly can't hold back his excitement (and this was evident in the Recode interview when he said Tesla's product roadmap was probably the world's most exciting right now).
Most of all was seeing Pickup prioritised higher than Semi+Roadster... two products that are already revealed and have full pages on the Tesla website.
I now think the request for Pickup features a couple of months back was to see if they had missed anything from their mostly-finished design. I think we're going to see it revealed in 1H '19.
Further... I think Elon really liked how the Semi+Roadster reveal played out, because the Semi was predictable, but the Roadster gave the media the extra pizazz that they needed for even more coverage.
Doing this the same way for the Pickup would make sense - especially if it's only for effect, with actual production further out.
The Model Y will garner a lot of interest at the reveal, but basically we already know what it is going to be - a 2-row CUV adapted from Model 3... will visually look like a blend of X and 3. (They could even go all algebra on our asses and use
X+3=Y in their marketing event promo.)
However, if they shock the world with a surprise BEV Pickup reveal at the same event, American truck companies would shyt a brick, *and* truckbuying activity at dealerships would fall off in the same way that BMW/Infiniti/Acura etc. dealerships saw crickets after the Model 3 reveal. Slowing down sales of ICE pickups is a part of the Tesla Mission. Even if the actual production of the Pickup might be a ways off.
It would be fun to show off the Model Y tow hitch at the reveal event. It pulls a big trailer onto the stage, on which is a huge shape wrapped in a cover. Elon says "I wonder what's under that cover, shall we take a look?" as the crowd screams wildly. OK I'm dreaming...
