House shows in towns that get the TV shows, they're basically all for the kids and the odd hardcore fan who wants the chance to get up close for cheaper cost than they would otherwise. Even me, I considered going to the house show in Wildwood, but only because I was there, I could walk there, and it was something to do on my vacation. Yet I didn't go as I had other plans. It would have to take an extraordinary set of circumstances to make me want to do that in Philly. Fans like the ones on this board know that nothing is going to happen to advance storylines, they're just gonna be out there wrestlin'. It's different if you're in a town where WWE rarely shows up.
As far as overexposure, that has to be a factor. I was willing to go to an NXT house show this year because I don't get opportunities otherwise to see NXT live. And the crowd in there was great, so I'm sure a lot of other people felt the same way I did. Chances are over the next year I will only be able to see NXT in Philly or Brooklyn. Although their Baltimore show, which is closer to Delaware than Baltimore proper, has me thinking a little bit.
