In addition to the technical concerns of a PoS move, it will unleash a torrent of regulatory / legal issues vis-a-via "Howie Test / Securities" discussion. 

This Gordian-knot of issues: (a) Gas fees, (b) Miner dissatisfaction, (c) Legal ramifications, and (d) Will It Work? provides a terrible risk profile, so I completely understand his reluctance to move forward and continual kicking can down the road strategy. 

As it stands, if everything else goes "perfect" it probably still doesn't fix the gas fee issue...it seems to be a no-win situation frankly.

Yeah and that miners might hard fork eth because they won't get rewards under PoS

Is Vitalik realizing Bitcoin's design is better?

I call dibs on him being stuck not knowing what to do with eth development. Speciality "now" that everyone is waiting for that PoS magic to solve every problem.
