If you are looking for something that really reaches out and engages the community, both new players and experienced one, the should go with something that actually engages the community of players and has a chance to engage people who are not allready interested in the games. Things such as LARPS at conventions, such as the one done at origins. Off Course they do need to make sure people know about these events.
Dare I suggest that it's *good* to have events outside conventions, and using alternate methods of communication (besides "you have to be there in person"), for members of the fanbase who for one reason or another can't attend them? I'm not going to make Origins or GenCon ; they're thousand of miles away. What makes you think the community is more likely to be engaged at a con 90% of the community will be lucky to attend once in a lifetime?
There are different types of fans, and different ways to reach out and engage each of them. For some of them, that proved to be Winter Court. For others it wasn't. The same can be said for any method you can imagine.
Unless you've got serious evidence AEG did Winter courts at the expanse of ideas that would have brought new people in, why even make the claims? It's not like WC prevented the organization of LARPs, since WC happened (surprise!) in the *Winter*, when the major conventions were half a year away anyway.
