I'm with Keith. I support a couple of stores in the area, and spend an approximate amount at each one on a monthly basis. Its not a question of whether or not I'll shop at those locations, its a question of how big of a cut of my money GW is getting. Since 40k and Fantasy are no longer the only two games I play, and with prices bordering on the absurd, their share is getting smaller and smaller. I think I've spent $37 on GW this year. Conversely I've pumped hundreds into Warmachine, Infinity and other smaller games since I feel there's greater value there.
What I'd love to know is GW's long-term financial plan. I'd like to know how they plan on getting new players once the current market is exhausted (see: death, real life expenses taking over, new interests, etc). 6th edition looks command over $100 in start-up costs before models are even factored in ($75 rulebook, $13 Psychic Power Cards, $30+ codex). After than you'll need like 1500-2000pts of stuff. I suppose the starter box alleviates some of this if you're interested in one of the armies in the box (or if you know you can sell off components you don't require).
