I got the call from my dealership today - they just got their allocation from Nissan and are confirming that people who have pre-orders are still actually wanting them.
They've issued new contracts for signing.
I was told that the Protos will come first (which mine is), and the rest will follow. They are not expecting a test/showroom car until September/October, but said they expect me to be driving my Proto by the end of this month
At my dealership 20 people ordered Protos, and they've only been allocated 4... I ordered mine on the first morning they were taking deposits (just for reference).
