I'll admit to being more optimistic. I'm thinking the limit is in the pack supply, thus making it an issue of not enough parts rather than many things needing resolved and thus is a different issue that the S or X ramps.
Tesla has basically had 9 months to work the kinks out of the line. In the first 9 months, S went from 0 to 5k/ quarter and over the following 1.5 years only increased another 50%. For the X, after a low first quarter, in 9 months it was at 8,750 cars/ quarter (75% of current volume).
If they can build 2k/ wk, burst would actually be a good thing in that it shows the line is operating way below capacity. Again, if they can do 5k a week end of Q2, then as long as the parts supply keeps up, they will be above 120k for the year.
Absolute worst case, if Fremont can do it, they spend Q2 doubling the semi-automatic pack lines, and hit 5k in Q3 without the German line.
