What's the thought or plans for the future given you've clearly put a good amount of effort into making the boards stackable with various backplanes?
Is it only 'we did this to enable people to purchase multiple boards on this order', or perhaps 'we plan to offer opportunities to purchase more compatible boards throughout the year that have BitFury chips', or 'we see opportunities to keep providing compatible boards even if we have to switch chip sources', or (ominous music) 'we did this to get someone else to fund our own super-massive scalable mining rig, MWahaha!' :-)
Seriously, I can only put in for one board now (and have done so). But all the people commenting that they've placed multiple orders made me think: Should I be totally discounting the stackable nature because it will be useless for anything in the future? And, should I sell body parts to go for a second or more board now because I won't be able to get one later?

I think you're stressing too much. Even if you miss out - like what you're saying (which I doubt you will), is it such a huge deal to use a USB hub?
Thanks!
