With so much uncertainty in the world right now, there's no guarantee that upcoming episode of RAW and SmackDown will be broadcast over the next several weeks. All it will take is for one Superstar to test positive for COVID-19 and then the entire locker room could be forced to self quarantine.
That will leave WWE without a show, and so it probably won't surprise you to learn that Post Wrestling Sheet is now reporting that the company is considering taping the remaining episodes of RAW and SmackDown which take place before WrestleMania. As of right now, there's no word on plans for NXT.
Interestingly, this taping schedule is likely to include both the WrestleMania shows scheduled for Saturday and Sunday on April 4th, and April 5th. That would be done on a closed set to ensure that spoilers don't leak online in advance, and it's pretty easy to understand why WWE has decided to do this.
Nothing is set in stone yet, though, and this is likely just one idea the company is considering to ensure they can at least get to WrestleMania before potentially being forced to shut down and hold off on further live broadcasts.
