The latest email from the official club confirms that they will hold back Nightbeat to send out with the Seacons. They also mention that the membership figure Topspin is also delayed.

We are still waiting on the programmer to fix the bugs in the pre-order routine. As soon as you can pre-order these, we will send out an email. No rush as it looks like from the poll in the club forum that you would prefer for us to be able to ship them together instead of separately. We anticipate these arriving in late summer as the boxes are being finalized now. We could have shipped Nightbeat earlier but now we will hold them until the SeaCons are ready. This will save you shipping.
Also, just a reminder, there was an error in China and we won't ship the free club figure TopSpin until the end of this month. Sorry for the delay, we were sad as well... ;(
Thanks for your support!

PS. No, we don't have a location for BotCon yet. Still working on it, so keep watching BotCon.com!
