I've been buying the double-disc editions, so I hope these come out for everything. I guess it's got to go a little faster than it as at some point – maybe at some stage they'll stop doing the super-deluxe editions?
Anyway, my guess is that b-sides and some 'known' unreleased stuff is coming out on the double discs (like Rode All Night, the Alternative MacII stuff), and there will be an anthology-style project at some point with the stuff from the MPL vaults. (NB: my guess I basically what I want to happen!

)
Also, I think he should put Press to Play out as soon as possible. A lot of the sound of that album (esp Pretty Little Head and Talk More Talk, and the drums in general) is very now. Bat For Lashes' (UK artist Natasha Khan's stage name) new album sounds – intentionally or not – very Press To Play in a lot of places, for example. And it's such a carefully-produced album that I'd love to hear it remastered. And it's due a re-appraisal.
One more thing: is the McCartney Collection version of Venus and Mars (which I have) the same mix as the original? If it is, they need to remix V&M as well as remaster it, because that's the most badly mixed album ever.
