There's a new normal for now, but I seriously doubt all of the social distancing, face masks, and everything else is here to stay for the long term.  The influenza pandemic of 1918 was much, much worse than COVID-19 and whatever modifications to people's lifestyles that were made back then eventually went away as fear subsided--and eventually enough time passed and it just became a historical event (albeit a serious one).  I'm pretty sure the same thing is going to happen with the current outbreak, though it's going to take some time.

That's pretty much what I'm thinking, but I don't expect it to be an overnight change by any means.  People are just too freaked out, and we'll probably be seeing face masks being worn for many months to come.
