I thought I'd start a thread where we can start capturing the rumors and facts regarding Model X dates. From today's SEC Form 10-K / Annual Report (emphasis mine):
We are adapting the platform architecture of the Model S to develop our Model X crossover. We revealed a prototype of Model X in
February 2012 and plan to begin production in late 2014. This unique vehicle has been designed to fill the niche between the roominess of a
minivan and the style of an SUV, while having high performance features such as a dual motor all-wheel drive system.
