I haven't been really impressed with the marketing campaign. It is kinda like GW is showing us a "mystery box" and taunting the fact that we know what's in the box but not the details.
I think Faeslayer is right in that my hobbying has slowed down a significant amount. I'm finishing painting up some daemons right now but I have not drive to purchase anything new because I don't have a clear enough picture of what to expect.
If we were give this month's upcoming WD last month I think that would be a lot more interest because people would have a more general idea of what to expect and can start planning their army accordingly. The problem is new editions have always favored people with larger collections because they have a greater ability to adapt to change. If the player base was give a little heads up about what is coming out those players will smaller collections can guide their purchases more aptly and be excited about it for longer.
