I am convinced that we will not see a refreshed iMac at today's event. With the iPad Mini, 13" rMBP, a new Mac Mini, iTunes, and iBooks, I cannot see it fitting in. I feel like they would want to spend a lot of time talking about the iMac and they probably want to spend even more time talking about the iPad mini, its just too many products for one day. Combined with rumors of shipping delays, etc, I think the new iMac is still a couple months off. We've seen this before with the original rMBP event. EVERYONE expected a new mac pro, Apple didn't (well, barely) deliver. There were simply too many other things going on. Does anyone else feel this way? I guess I'll be proven right or wrong in a few hours.
