I appreciate we like to speculate about his, but I don't think it's anywhere near this complicated for the band. I personally feel the tour format(s) & releases have seemed pretty loose & directionless for some time now. They're probably going to tour next summer because they want to play (as they've said many times); I think what they hang on this is now a total afterthought. I mean, the guys get asked stuff in interviews & don't seem that capable of articulating their understanding of their own discography; either that or they're (still) not that comfortable talking about their artistic output, conflating this (altho' perhaps this is more personal to them that I appreciate) with their own personal lives (which I understand they have no particular wish talking about). I thought the early history/retro tours were great; but the ME revisit was too long and not a good enough retrospective to be something I care to applaud them for doing. It's hard to tell whether the band themselves really care that much for these look-backs; beyond just enjoying performing & playing. It's just such a pity that the forthcoming activity might be another half-arsed retrospective when their time is potentially so short.
