They can block it out if the annual pass doesn't include Epic-- current passes only say they are valid for the current parks. When we're a year out from opening we'll know for sure if they offer a 3/4 park pass, or if they just keep the current passes and offer some kind of discounts for passholder to go to Epic. There's a chance that they just raise prices and include Epic, or they wait until they see how the park handles crowds first and offer Epic as an add on for an additional fee. If all the passholders go to Epic and not the other parks, it could be a HUGE problem. We might even see something like the single night HHN ticket offered for top tier passholders to go to Epic once with their pass, at least to start.
