If you check the home page, the list of top miners, there are many such miners with exactly the same hash powers.
Moreover a couple of them were found with multiple 26 GH/s workers. This makes me believe about the possibility of multiple ASIC miners.
Doubtful there are ASICS. Likely there are FPGA arrays crunching away, but ASICs wouldn't be able to have this much silence if they existed yet.
There are a few server builders out there and last I checked Bitworks has a ~130 MH/s ETH rig in a 4U server chassis. 20 of those to a single address and bam you got 26 GH/s. Wouldn't doubt it might be Bitworks themselves using that pool for burn in too...
Who knows... but ASICs aren't a concern yet, and they can be dealt with in these coins.
