It looks like they are going to do just that. Tesla is very close to 200k this month and that is probably partly why they shut down to "improve production rate". Slow down production in June to not hit 200k until after July 1. They have also been playing with exporting more cars to hit the 200k number at just the right time.
Having the maximum 6 months instead of the minimum 3 months will be a lot of extra cars/people getting the tax credit. If they average 6000 cars a week over that time (12 weeks x 6000 x $7500) that is an extra $540 million.
Then the tax credit goes in half for the next two quarters and in half again ($7500/4) for the next 2 quarters.
Seems a bit strange for the law not just to say the credit extends for 6 months after the 200,000th car is built, but who knows how such laws get crafted.

From a page linked on the page you gave:
"The new qualified plug-in electric drive motor vehicle credit phases out for a manufacturer’s vehicles over the one-year period beginning with the second calendar quarter after the calendar quarter in which at least 200,000 qualifying vehicles manufactured by that manufacturer have been sold for use in the United States (determined on a cumulative basis for sales after December 31, 2009) (“phase-out period”). Qualifying vehicles manufactured by that manufacturer are eligible for 50 percent of the credit if acquired in the first two quarters of the phase-out period and 25 percent of the credit if acquired in the third or fourth quarter of the phase-out period. Vehicles manufactured by that manufacturer are not eligible for a credit if acquired after the phase-out period."
I believe this somewhat convoluted language says the same thing I did. The phase out lasts a year. 50% for the first 6 months and 25% for the next 6 months. This starts after the end of the first full quarter after the quarter where the domestic sales are greater than 200k (ie, between 3 and 6 months after 200k sold).
1) Short your stock.
2) Hold press event.
3) Get cagey about questions.
4) Profit.
For example giving an uncharacteristic pregnant pause when answering a straight forward question or becoming agitated when normally you're subdue?
If a company is giving regular updates on production and targets and then gets weird about it for one meeting then you can expect a drop. It looks like they are back on track (and are again open about production), but you can bet if they get cagey about it again their stock is going to take a hit. They might be able to transition to less openness if they want to (so they only reveal what they want and don't spook investors), but not one extreme to the other in just one shareholders meeting.
