As verified with Mosaic several years ago, the big boxes are sold in sequence, but the Selects are not (in fact, the newer Selects aren't even individually numbered).
Thanks. It was an idle curiosity. I've never noticed, do they ever say that a license on a big box is set to expire on X-date, rather than just categorize it as "running low?" Might be helpful for a buyer who wants to prioritize things. But maybe there's a legal or proprietary reason that they would avoid doing so?
No, as Hans indicated, Mosaic never publicly reveals exactly when a particular license is due to expire. They also never indicate the reason--i.e., either expiring license or exhaustion of the authorized run--a particular set is "running low" or in "last chance." Presumably, this is proprietary information that, for marketing reasons, they don't want to reveal.
