How much do you reckon they'll be priced at (with or without the chips)?
Probably very close to or more than what they will return in their lifetime.
hopefully the price will be set <2BTC at this point
Not even sure you would make ROI at <1BTC. Even if you has it in hands today...
work on your math. assuming the boards run at >30GH without overclocking, you should be able to see 2BTC return within a few months, and the bitfury chip is pretty future-stable (on par with many 28nm designs when underclocked)
