We know Power, Corruption & Lies is coming in November, so I'm predicting two per year:
Spring 2020 Low-life Fall 2020 Brotherhood Spring 2021 Substance* Fall 2021 Technique
* A key album, collecting many non-albums singles. Broke them in the U.S. Would include all the remastered 12" singles being reissued, since they've only had vinyl and digital formats (the first four left out of Movement).
I would love to have one for Republic, wrapping up New Order mk. 1. I personally don't feel Get Ready and WFTSC deserve them, and everything from Music Complete is largely available.
I would like to see a DVD release of one of the keyboard orchestra gigs, along with the documentary.
