In my opinion, I think that this really is the beginning of the new crypto era(although it has started long ago, I pretty much think that this year will be the determiner in my opinion). And the news you are saying are just one of the greatest and biggest that are yet to come within this year. But regarding the regulators, I don't think that they will be backing down. Because clearly, the non crypto people will not make money out of the cypto world without regulation. Not to mention their best over used alibis like bitcoins can be used for crime and can make someone lose a lot etc., which has some touch of truths in it to be honest but come on, we ain't that dumb to not see what they are really doing. So yeah, I think regulation is the only way to go if we want mass adoption.
