Steve,
No offense of course, but yes, I think you're being overly paranoid
.
Tesla's relative silence lately has a great bit to do with the fact that they're in the middle of the IPO process. It's not uncommon for companies in this process to "go silent", as they want to avoid anything that might have the appearance of upsetting the investor apple cart (as I understand it). I think a lot of people are interpreting the silence as a problem. It's really not, per se.
As far as the discontinuation of the Roadster is concerned, my understanding is that they are merely stopping the product line in order to do re-tooling at the factory.
Besides, folks are still getting reservation spots for the S that have expected deliveries of Q2 2012.
Tesla's had a lot of good press, they've stated that reservations for the Model S have exceeded their expectations so far, they've got DOE loan approval (which would've required a convincing business case for the DOE to approve the loan), they're hiring like crazy, and...well...I wouldn't worry too much.
Will the S be late? Maybe. Chances are decent that they'll probably be at least a little late coming to production. But so far, indications are that Tesla's on track. We have to remember that the car's not even expected for another 21 months or so. No reason to speculate now.
Tesla's already done some incredibly impressive things, proving to the world that the general public's perception of EV's is wrong. We just have to give them the time to work everything out.
My two cents. (that's a lot to type on a smartphone!)
