I heard $200M, which really isn't, tho (in terms of corporate development, obviously I could live the rest of my life on 1% of that). Plus, they're counting on this as the "weenie" for what looks like Church St. Station 2.0. The money isn't necessarily in the coaster, it's in finding something to attract the convention crowds to eat and drink.
That iSquare mall/hotel, tho--I think it's probably killed by this.
