You know, it's really interesting. The closed Facebook HHN group (which has 10,000 members so it's truly closed) did their own anticipation poll. That group is way more casual than the forum crews, and it shows just how effective IPs can be in regards to driving excitement. An original cracks the top 5, but it's not the same as the die-hards' pick (Ghost Town), which doesn't have half as many votes as Lunatics.
But yeah, for all the talk about IPs not being effective even the most casual polling indicates otherwise.
