That term gets thrown around a fair bit without meaning to sound condescending. A better term would be "focussed" or "desperate"... as it suggests that a person is more passionately keen to acquire certain key figures or complete a set or series. Using the word "true" is very subjective, and gets some people defensive, when it isn't being intended as an insult.
Wow... it was there just a couple hours ago when I posted about Soundwave's page being taken down.
It shouldn't have sold out already. Perhaps they are just trying to prevent over-selling it like they probably did with Soundwave.
