In practice the discount will be available until we've sold the first batch of 1000 units. If you want to be sure of getting one of these you'll have to order fairly quickly - if you leave it for a while, and we've sold the batch, you lose out.

The discount isn't really the main issue there - the issue is that we're allowing existing clients to skip the queue and get a Mark 2 ahead of the other 10,000 or so clients that are waiting.
