Customer features don't tend to be catalysts. If the surprise today is nicer interior, bells, whistles, spare tire whatever, that is good for the company long term, good for consumers etc. But not a catalyst for short term trading.
What WOULD be? High reservation numbers, a bullish update on the ramp, gross margin comments, etc. None of which I expect at the handover event. It will be a consumer focused party, its not a make shareholders happy party. Those things would come out in the ER in 3 days not tonight. These parties tend to be about congratulating the team for making what they said they would and getting lots of applause for stuff we basically know.
