I refer to all of that music as "mall-core", admittedly in a condescending way because of the teenage Hot Topic regulars that love those bands, and the fact that I don't like any of the bands that you just listed in that first paragraph. It's the type of thing where if it extends into what emo actually is, I'll be sad. The new Into It. Over It. and TWIABP are gateways into the genre. That said, it's going to lead to a couple of routes. The one that lures people in and makes them think they like the genre, when in reality they've only listened to one of those two bands. The other is more exciting, and one I think you should be excited for too, it's the one where it leads to people delving farther into the genre and discovering more of these great bands.
