Point is, I think both WotC and Paizo are doing a good thing by getting rid of the random collectible aspect of minis.
As a one-off, the beginners box could do fine, but as a continuing line randomized seems to be the way pre-painted plastics sell best overall. That's how the vast majority of WizKids minis are already sold.
Randomized boosters work great for expanding a collectible line indefinitely, but that is not compatible with the goal of a long-lived, popular line of minis for supporting RPG play. That model would be the "stuff people can use" approach, exemplified by Legendary Encounters line by Reaper. While a smallish line, it has continued to sell and to produce new models steadily.
This has simply shown to be false in the marketplace. Reaper's Legendary Encounters are a small line and made up by a lot of singles also, is rather small and doesn't produce many new models at a pace of a major line. They're also generally more expensive.
Will that be enough for some gamers? Sure, but people getting in at the ground floor are left woefully behind. Merric's Law of Miniatures is a pretty good general guideline.
