I'm assuming the potential rewards from here on will mean the vast majority of nodes will have similar specs and be managed pretty well, and the pools will punish operators who run unreliable nodes. Too much money on the table now!
I agree, notaries will be be professionally managed, @ 50USD the KMD marketcap is still only 5bil USD, and that yields 75K USD per month for each notary. I expect this by Q1 2019.
