Part of me doesn't like this. But the other part still remembers its "tabletop days", where it was a Games Workshop addict... I guess you know where this is heading - GW stores are about the worst thing any sane gamer could imagine. If those WotC stores are anything like those... (I don't know, 'cause I live some thousand miles away from the closest WotC store)
That personal dislike aside, I'd say that, well, big companies are like that: to raise profit, you've got to cut the less profitable "ventures". Buy what you can, drop what doesn't hold up to expectations. Like their retail stores, obviously.
Don't draw easy conclusions from this incident. It doesn't necessarily mean that WotC is in any danger of being closed by Hasbro. Not necessary...
