With all the money going into R&D, I also think it's likely that no one is going to be able to squeeze any meaningful efficiency increases out of the current ASIC form factor before the next generation of gear becomes available. At least not in gear that will be made available to small miners like you and me.
Back in June we ordered a fairly big batch of 13.5TH S9's from Bitmain for Sept delivery. At that time they were selling them for $1113ea. That was $82.4 per TH. I'm not sure the June sales batches were the cheapest they had ever sold them for either. Even though the current price for January S9 units is $104/TH, it is clear that Bitmain can easily sell S9 units at or below the cost of these DragonMint units on a cost per TH basis. A Jan S9 will include 2 months of mining yields that a DragonMint unit won't. Right now that would be worth several hundred $ per unit.
The Halong miner in pre-order is $84.3 per TH. At the regular price they will cost $99.68/TH. Not particularly competitive. They are not notably more power efficient than current gen with advertised specs. Quality is utterly unknown and unproven in the field. These guys might have a 25% field failure rate in 6 months for all we know. You have to tie up your BTC for 4-5 months and take the risk that this company can deliver when promised at the specs promised. Most notably, you are committing capital to a form factor close to the end of it's life cycle.
It bothers me when a company needs to raise production revenue by pre-selling $M worth of machines 5 months in advance (the hardware equivalent of an ICO), machines that do not offer any real price/production advantage over a unit that has been on the market for over a year and a half. It also bothers me whenever a company tries to tug at your sensibilities with one of these 'decentralize crypto' campaigns. That sort of marketing is bullshit, like "hey, we're on your side bro - don't bow to the tyranny of XXX, we've got your back instead." Yeah right. Trust and believe if they had a superior product, they would try to monopolize the market just like any other company. So many people in our community like to line up behind 'their favorite company/whatever', and these companies naturally try to leverage that where ever they can, but none of these companies are looking out for us.
If Halong is legit, then we may have another equipment alternative soon and perhaps an incentive to drive down the prices of other companies gear (which in itself is a double edged sword), but aside from that, I really don't see anything compelling happening here.
