I'm in the boat of keeping my expectations in check, now does this year look good? Well considering I'm seriously planning on attending this year because of the lineup, that's a resounding yes! But when you keep expectations in check, you can avoid overhyping yourself a la' 20 Years of Fear*.
* = A year I find fascinating, the potential of the lineup was through the roof, but that year out of all the others seemed to suffer the most from overhype be it from guests own expectations, hype from A&D/Marketing...and the overall execution of some houses which weren't the homeruns they could've been. (Lookin' at you, Hades, Legendary Truth, The Hallow'd Past (But mostly 2008), Echoes of Shadybrook.)
