You and me are on the same boat about wondering if it'll be worth it (for us), to visit the parks soon after they reopen. Pretty sure that the changes will be very noticeable at the beginning, but I'm hopeful that in time, procedures and capacities would be tweaked. I'm not so sure if things will ever be the way they were, before this crisis.
A deal breaker for us, would be if EPCOT is closed during the time we're planning to visit. I hope we learn more about what to expect as soon as it is possible. Only then, will we be able to decide if the new conditions are worth it for us.
I'm finally beginning to disconnect from our upcoming WDW visit too... and just like you, all that is left for us to do is, officially cancel.
