we took preorders on the 2nd gen
We're in the 2nd gen.
Once the spec is known, it's not preorders anymore.
It's backlog of orders.
I know the point that you're trying to make, but I'm afraid it's not valid.
If you're not shipping from stock, you're taking preorders, whether you have the specs are not.
This is only fair, because anyone can say "we have the specs" and "we've taped out", even though they don't and haven't (see BFL, BA).
