You guys do realize that wildkeccak already has fpga miners in development for it, right? I dont see a scenario where they wont be made for a v2 either.
Regardless of power consumption, your gpus arent going to compete with fpga's. either way if zano is profitable enough theres more incentive for them to be created and a good chunk of the network will belong to a select few with the knowlege and resources to make/obtain them.
Just some food for thought.
