Black Arrow announces delay for Prospero X-1, X-3 and Minion cloud mining orders

Unfortunate news, though props to them for being transparent about the delivery delay:
"We have to inform you that our schedule to manufacture and assemble the system has been disrupted and we are unable to make delivery of the Batch 1 Minion ASIC chip on the initial scheduled date (end of February). We are now expecting to dispatch all Batch 1 orders on 1st of May 2014.
Please be re-assured we are confident that we have tried our best to accomplish our initial ambitious targets. However, we came to the conclusion that it is in the best interest of our customers to delay shipping in order to ensure that the product provides the best-possible user experience.
Without this delay we would have achieved 1.5W/Ghash which would have meant that our chip would not have been competitive at all.
We have now finalized the design process using our newly improved code and will start manufacturing the chip (tape out) in the next few days.
We are happy to announce that Black Arrow Software’s products remain on target for being the best in their class for power consumption. We confirm that our latest improved design has the following technical specifications:
·0.75w/Ghash on TT corner @ 25C which is expected to run at 120Ghash/sec.
·SS corner will be 0.6w/ghash and will run at 100Ghash.
·A further underclocking and underpower should be possible and should yield 80Ghash @ 0.5W/ghash. However, please note that this is not guaranteed to work stable.
Please note, that a further push for improvement in the optimization process would have guaranteed further delays for at least 1-2 months.
It is no secret to us that the Bitcoin mining process is proving to be more and more difficult every day. To compensate our loyal customer for the unforeseen delay of in delivering our miners for batch 1, we are happy to offer free extra hashing power which consists of 25% of your purchased hashing power from our Rent-Some-Minions cloud program for 4 months.
The account for the tape-out has been settled in full and we are confident that the delivery will be completed shortly.
We are taking all the necessary measures and positive actions to expedite delivery to you as soon possible and we are confident that we have the resources to be successful.
Please note:
·We estimate that the delivery for the Batch1 will coincide with the delivery of the Batch2
·The delivery of Batch2 remains unchanged
·The one-off offer presented above is open to the customers who placed orders for Batch1
Sincerely,
The Black Arrow Software Team"
EDIT: I received an e-mail message on 01/31 seemingly agreeing to provide me with a refund if I wanted one, less a $50USD service charge. They also asked me to consider waiting a few more days while BA explores alternatives to the 25% bonus compensation they previously offered. I assume nearly everyone who has complained recently received a similar message.

Black Arrow recently announced the issues to be resolved and that both X-1 and X-3 miner orders would be dispatched by the end of July. Together with the company’s latest news update, the option to convert pre-ordered miners into bare ASIC chips was provided, implying that each X-3 order could be exchanged for 100 ASIC chips, whereas you would get six chips for an X-1 order. 29/08/2014, Shenzhen, China; Black Arrow, a Bitcoin ASIC manufacturer, announces that it has been working towards building its next generation Bitcoin ASIC since the tapeout of its last ASIC (March 2014) and it has now set a tape-out date: December 2014. This new Bitcoin ASIC will use the 14nm FinFet process and the power consumption target is 0.3J/Ghash at chip level. Furthermore, Bitcoin ASIC technology keeps getting faster, more efficient and more productive so it keeps pushing the limits of what makes the best Bitcoin mining hardware. Some models of Bitcoin miners include Antminer S5, Antminer U3, ASICMiner BE Tube, ASICMiner BE Prisma, Avalon 2, Avalon 3, BTC Garden AM-V1 616 GH/s, VMC PLATINUM 6 MODULE, and USB miners . Application-specific integrated circuit (ASIC) chips are bitcoin mining hardware created solely to solve Bitcoin blocks. They only have minimum requirements for other normal computer applications. Consequently, Bitcoin ASIC mining systems can solve Bitcoin blocks much faster and use less electricity or energy than older bitcoin mining hardware such as CPU, GPU or FPGA.
