Despite being so close to the launch window of the Model 3, which will be revealed tonight (March 31st) in Los Angeles (and of which you can watch live here if you are not lucky enough to be one of the 800 attendees), Tesla CEO Elon Musk took to Twitter to put the Model 3's debut into context, and set some expectations of the event - saying not all will be revealed.

Naturally, this revelation that we won't be getting the whole picture on the Model 3 immediately (some 21 months before the actual launch), threatened the space-time continuum, as question after question was posed in response to Musk's tweet shortly thereafter.

Seeing that the stars in the sky were no longer in motion, the Tesla boss managed to answer one question about his cryptic tweet, saying the Model 3 will still clearly be on display at the event, before having his phone was confiscated by his handlers returning to silent running.

Why won't everything be revealed?  Just ask Carlos Ghosn about the next LEAF, and watch him clam up. Tesla is now facing one of its first "big boy" problems - an existing product portfolio (and revenue stream) to concern itself with when launching a new offering.

So, what will be "added", what will "evolve" when it comes to the Model 3?

We could suggest pricing disclosures, and those features which might threaten Model S sales in the interim would be top of the list.  But we digress, as everyone needs something to speculate on until 8:30 PM (PT)/11:30 PM (ET) tomorrow night!
