If it's anything like the store in NYC, it will be merch heavily based on NBC properties, many of which have cult followings (Community, Parks & Rec, 30 Rock, etc) along with old-school NBC properties like Seinfeld. Plus also expect lots of merch/photo ops from things like The Voice, SNL, Jimmy Fallon, Seth Meyers and The Today Show.
They do really good business at that store.
