On the contrary, it might do just that. Simple economics dictate that more the people you stuff into the ground, less you need to take from them individually - and still end up making a sizeable improvement on your present earnings considering the increase in numbers on matchday rise by 50% compared to current levels in a 60k stadium. Thus, cheaper tickets bring in more of the local, vocal lot who obviously enhance the atmosphere. This is of course, assuming that we sell out the proposed 60k seats every week. Also, ticket prices currently wouldn't increase sharply either, I'd imagine, as costs associated with stadium redevelopment are not under the purview of UFFP, calming fears that the proposed move would result in a large hike.
