@Mr. Mystery: I'm not sure why you always default back to this notion that how other games are doing matters. We aren't talking about them. They are unimportant to this discussion. Hell, Games Workshop always insists (as do many people here) that their competition doesn't matter. Ultimately, whether or not other game companies are doing poorly has no bearing (nor is it a valid excuse) for a poor performance by Games Workshop. However, I will briefly entertain the other companies since you seem to come back to them so often. If things were "tough all over" as you like to imply, saying that we just can't see it because they aren't public...
1. The number of competitors (new companies) decrease when things are tough for everyone... the opposite of what is happening right now.
2. If things were "tough all over" we would see some of the weak, smaller companies failing. That is what happens when you start up a new company in a bad market.
I think it is safe to say that all all these new, smaller companies seem to be surviving for now. That is an indicator of a healthy market and that they are stable and/or growing. Small companies must grow to survive. Only large companies can handle multiple quarters of stagnation or shrinkage. Now that we have that out of the way, let's go back to Games Workshop.
The shortest distance between two points is a straight line. This can also expressed as, the most obvious answer is normally the correct one, or where there is smoke there is fire. We can try to come up with all sorts of elaborate reasons or excuses for their continuing drops in sales, customer animosity, treatment of independents, bubble business culture, and savage cut backs and firings within their own company, but what would be the point? All of these things are well-known indicators of a company with serious problems.
