Well, logically, I'd have to assume that much of what is classified as pre-release apathy is simply that people have exhausted the content in general terms?

However, the sigil example you gave is definitely one of the rare examples of inflicted apathy; I'm a believer in the band-aid school of revising myself, and would much rather such improvements land out of the blue rather than be preceded by weeks of "YOUR CURRENT ACTIVITIES WILL SOON BE OBSOLETE MWA HA HA" pre-warning.
