Music-wise, that would be great.
Touring-wise, I don't see that happening. Janet is definitely waiting to kick-off the project until she can -at least- announce the new tour dates. She won't make a profit if there is not a tour.
Chances are big that we can actually return to concerts early next year, and maybe even later THIS year. However, nothing is certain yet, that's why Janet hasn't announced any dates yet.
