My point is that more people are going to start talking about when this actually is going to end, and maybe then you will hear something from the leagues about when they intend to resume.
Silent? No. They're not silent now, and won't be then.
Have they been discussing options? Of course. Most have gone through Plan A and B and are on C but preparing for D and E and so on.
Have dates set for resuming play and announce those dates next week? Unlikely. Not impossible, but I'd bet against the NBA and MLS doing so. I'd probably wager against the NHL also, but I have no sources there.
Right now it seems like taboo in society to question the economic response to the coronavirus but that is going to change real soon.
