I think maybe Ed is on to something. If it really is just an iMac, then Apple would have to know that they were setting themselves up for a let down. Furthermore, everyone has been screaming flat panel iMac for months, and to say "way beyond the rumor sites" would really be setting Apple, Steve more specifically, for one of those "we blew it this time" comments. Just my opinion though. I could care less what they release, I'm sure it will be cool regardless of what it is.
