Was wondering about Nightbeat, and this posting by the BotCon people says it:

Everything is going out in waves, those who ordered just the Seacons, those who ordered both, those who ordered just Nightbeat. Not necessarily in that order, but there is a madness to the method
I think all the bulk orders here had some of each, so we could be getting ours sent out a little later if they are shipping single items first and working their way up to the bulk and mixed lots.

And this apparently from Brian himself:

The sequence is all single orders SC or NB then orders that have
both. We should have them all out by the first of next week. It is just
a lot of orders.
Thanks,
Brian
