With ASICs it has always been on the cards that suppliers with their own ASIC would retreat into just supplying their own mine. This might be for the reason of protecting their own rig earnings but at a more basic level if you are making a low profit on hardware why have the hassle and costs of customer support, logistics and the chance they will not pay you if the market goes the wrong way. Hopefully Bitfury ASICs will become available again at a reasonable price but given my statement above they might not.

We are now in a period where the market will start to become more stable. It won't stop growing but the growth will become more controlled. X200+ growth in hashing power in the last year has been somewhat explosive. With ASICs appearing already at 28nm it is unlikely that newer ASIC technologies will offer much over these in cost reduction for Bitcoin in the short term so there is unlikely to be big advantages in people doing technology jumps like we have seen in the last 12 months. So it will be down to more of a grind, low margins, and how much your electric costs. That might mean a handful of super-rigs in the world, based in low electric cost sites, and basically controlled by ASIC producers with 90% of the network.
