Turns out there's a Sony store in Philly at the Comcast tower thing (that's gotta be like, the nexus of all corporate evil or something).

Anyway, it was $50 down and came with a spiffy little card. The guy that took my pre-order said they weren't sure if it was going to be a midnight launch because they only stay open when that building is open, but he was confident that everyone that pre-ordered would get a system on day one.
