my source doesn't know much either, only what I've already said. I would assume that they'd be using the same masters for the Disc 1 of each of these re-releases, meaning they can either get rid of existing overstocks of the current discs (which may have been a motivating factor behind this release), or replicate cheaply off masters that are already sitting there.
It's still early in the game. What a great summer to look forward too
