I've been really liking GW the past year, as a fan. When I started the hobby just over a year ago, I was appalled that GW released new editions of the game without updating every codex. Veterans laughed and said, "Oh, you." Well look at 'em now! Shouldn't be much longer until they're all hardback. Supplements and dataslates are a tough pill to swallow but really do provide an avenue for providing new content, and you really don't even have to buy them to use their game rules.
As a consumer, I still only make purchases through third parties and eBay. I don't think that will ever change. There's practically no reason for me to ever pay retail prices.
