Reaction haven't gone bust, as far as I know, but due to various things I wouldn't hold your breath for any further figures in that range right at the moment (because you'll turn a strange shade of purple and eventually die).
On a brighter note, work is continuing on the prestige range of sculptures - Dredd is already available, and Death and Anderson will be with us very soon (as will the online shop, where you can buy them), and we've got people working on a range of 4" metal figures.
