After some digging found:
https://github.com/EggPool/BismuthHowto/blob/master/Masternodes/masternode.MD
and
https://github.com/bismuthfoundation/masternodes/blob/master/doc/HyperNodes_FAQ.md
So a node right now is ~$5400 usd (10k BIS)
Requirements as far as hardware are a bit more than other masternodes but this is expected because of difference of hypernodes vs regular dash based MNs.
It's interesting that it will have a separate POS chain but no currency...the nodes but me rewarded with BIS somehow but how and where will that come from?
Will wait for more information about this but following..
