I'm having my Ghost edition shipped. I wont have it at midnight, but I'll be avoiding kids bossing around their moms at midnight launch and wont have to worry about my ediiton being unavailable. As long as Amazon upholds their shipping times!
I might give it a digital download to play it at midnight (yay disposable income), but that's usually when the servers are overloaded, so it probably isn't going to be as exciting.
I'll be doing digital and pre-load. The servers will definitely be packed on Sony side but I'm a firm believer in first come first serve so if I get in with the first legion bum rushing the server and never log off I hope I'll be ok.
