let me tell you this. Apple officially stated that the iMac will come before 2013. That's it. Nothing more to it. If Apple lied it would hurt their business a lot so your statement is wrong sorry to say.
No, apple actually stated nothing at all about the iMac, the only thing they did was clarify that when they spoke about a 2013 update they were only talking about the mac pro, at no point did they say the iMac would be released before 2012 or even after. I've been playing the waiting game for this since CHRISTMAS so I am not trolling as a lot of you seem to think anyone who does not think a refresh is coming this year is. I want it as much as the next guy but let's be realistic, there has been absolutely nothing concrete with the possible exception of the benchmark back in April, and even that may not be real, so far it was definitely being refreshed in march... Oh sorry, April. It's been delayed now it's coming may 5th, oh crap, well its gotta be WWDC in June, oops that was just portables, well it will be with mountain lion, that was always the most logical date, wasn't it? Now sept 12 or maybe October. Need I go on? As much as I'd love to gt rid of this near dead 2005 dell laptop I am not going to pay full whack for early 2011 tech, and to be fair, by October (doubtful) ivy bridge will be half way through its life so MAYBE apple are waiting for Haswell since ivy was mainly for portables? Logic will always triumph over hope and despair.
