Although everything can change (as I've stressed before), this is roughly what I've already suggested fits the pattern of both Mark and Bob and also fits what little has come out by way of rumour.
Needless to say, I wouldn't describe any BD/MK tour as a distraction. A bonus for you is that there is a chance that you will get to hear a few more songs from the new album. There is a difference this time, as I understand things. As the result of singing new songs during his previous outing with Dylan, Mark decided to change one or more of those songs for the new album. Please tell me if I've got this wrong but that's what's in my mind.
If Mark's new album were to be released in September (or thereabouts), surely he will play some of the new songs live in October and November (and that's still my favourite period for any joint tour, assuming it does happen). Dylan was working on a new album in January and February, so that could well be out around the same time as Mark's new album, so he might be stick a few new songs into his set.
Should they tour together then, it could be quite enticing to attend a few shows.
