This is good news, actually.
Anyone who expected tours to start earlier than next August was probably not paying much attention to the stated consensus of the scientific community and current events, or being realistic. Honestly, August is probably still a pretty optimistic target for tours, so I wouldn't start making firm plans yet. It's worth noting: they're still not accepting deposits, so in a way, all they've really done is acknowledge that the tours ain't happening anytime before August, the rest is still officially "ask us later, we'll see." But...this is certainly better than their crystal ball telling them to remove listings for tours all the way through the end of 2021. Glass half full...
My own guess for a while has been that, if all goes well, then independent travel should start opening up around the end of summer 2021. A couple months ago I made my bet on September for a (non-tour) trip to Europe. I've started making flight and hotel reservations for September -- but everything I've been booking is fully refundable. I'm still being cautious, I figure there's a 50/50 chance we will be able to go then.
We've been getting a lot of hopeful news on vaccines in recent weeks (now 3 different vaccines coming soon, 90%+ effective, and several more close behind that we should be hearing about soon). Though it will take some time to roll them out, I'm feeling more optimistic. We have a few rough months to get through first, though. Everyone please be responsible and stay home (listen to the wisdom of Samuel L Jackson...), remember we all have a hand in limiting the spread of the pandemic. Don't let down your guard, be patient, light at the end of the tunnel, the cavalry is coming, etc.
Let's hope next summer brings all the openings we are hoping for. horsewoofie, I hope you are doing fine - we all need to take care and get through the months ahead.
