Last I checked, "real" PoS was at least a year away, and receding fast. The current testnets are so lacking in functionality I'm not sure they can be called PoS.
Unfortunately, many people don't understand the actual dynamics of all of this and they equate ETH2 phase 0, which is supposed to see the light of day this year (I'm personally doubtful of even that), with the 'end' of PoW. Nobody in their right mind would trust many billions of value to some brand new unproven consensus model.
That said, if they think they can make it work, I'm all for letting them try.
