Almost half a billion dollars. Amazing.
Deposits aren't the exciting number. Just ignoring the huge rate of new accruing reservations, 455k reservations with an average sale price of $43k is $19,6B in revenue, which - with Tesla's goal of 25% profit per unit (if I'm remembering right, correct me if I'm wrong) would be 4,9B in profit (before non-production expenses). Just from today's preorders. And a net of +1800 per day on the reservations is an annualized 657k reservations per year (although one expects it to slow, it's been boosted by the launch event... but then again, they could turn up the PR on the Model 3 any time they wanted)
Tesla has the recipe for success sitting in front of them. They just need to get through "production hell" and get the cars out the door, without ruining their reputation (and thus future profitability) in the process. If Tesla sticks to their schedule and the Model 3 isn't plagued with bugs, they will be an established, profitable automaker with a solid, demonstrated customer base.
