Today is Jan, 5, almost Jan6,  and from amount of information  BlackArrow has released so far, it seems damn near impossible for them to  finish the first batch device, not saying all the devices but device, by Feb-24 as they had put on website.

• They haven't announced tape-out
• forget tapeout, their FPGA testing were 33% less efficient, it seems.
  I really commend that, they decided to put 33% more chips to make-up the hash-rate rather than giving 33%less.hashrate.
  
• They have showed the heat sink pictures
• Started with 2U but from their own website they have moved to 3U

I have all my eggs in Blackarrow basket. 


I am so secretly hoping that someone will come up with data indicating, Black arrow might finish Prospero-X3, by Feb-24.
May be blackarrow himself will comment on this thread. :|
