I think I will be waiting for dense Gridseed based hardware, but nice to see them in the wild at least.

For those defending GPUs as more profitable:

GPU:

Energy hungry
Hot
Hard to scale at a point without industrial cooling and power
Less up-front cost, but long term pain due to the above

ASIC

Energy efficient
Much less heat
Easier to scale (Simple USB hosts compared to also needing an entire PC to run multiple GPUs)
More up front cost, but savings in the long term due to the vastly increased efficiency.

Pluses and minuses as with all things. Anyone spouting off about how GPUs are so much superior are not considering all points.
