I'm expecting the X ramp to be slower than most people think. A while back (maybe the Q4 2014 call?) Elon stated the ramp for the X would be considerably faster than the S when discussing the latest X delay. Since then I haven't heard that sentiment again, and any time the launch date is brought up he refers to "first deliveries" and doesn't mention volume production.
No, he keeps saying that the X ramp is going to be significantly faster. But of course, the S ramp was not particularly quick. They shipped 2,438 in Q3, then 5,204 in Q4. I think they are expecting much more than that, but mostly in Q4.
The issue is the start date. If they don't really ramp in Q3 at all, that will be seen as a negative in the short term, even if they do end up catching up to 55k for the year. The big issue is that the market won't believe them and there will be a short term reaction.
