So here we are - Mid-October, 2012. It's been over 500 days since the last iMac update. It's also about 6 months away from Intel's release of their 4th generation core processors (Haswell processors). Intel has already been demonstrating working Haswell systems on display at various keynote events. Will Apple decide to release a new totally re-designed iMac with processors that have already been available for 6 months now? At this point, I don't think so. Apple recognizes that there is not much of a speed bump or performance upgrade between Sandy Bridge and Ivy Bridge processors, at least not enough of a speed or performance bump for the common iMac user to notice. Sandy Bridge processors and Ivy Bridge processors both use the same CPU socket (LGA 1155). This similarity would have made it very simple for Apple to update the iMac line with Ivy Bridge processors because they can most likely use the exact same logic boards and components. Haswell chips, on the other hand, will use a new CPU socket (LGA 1150). The idea that Apple would decide to completely re-design their internal iMac components for a new generation Ivy Bridge iMac now just doesn't make sense to me. They would have to re-design all the components again for a Haswell iMac. I believe that if Apple wanted to release an Ivy Bridge iMac they would have already and it would look exactly like the current generation iMacs. My prediction is that there Apple will be amongst the first computer makers - if not the first to sell Haswell systems. These new iMacs will be a major re-design. Screen sizes will stay the same, but resolution will increase. the 21.5" iMac will have a 2560 x 1440 resolution (the same as the current 27" iMac) and the 27" iMac will offer a 2880 x 1800 display. There will be no optical drive, and all flash storage. Also, the new iMacs will be the first generation to support 802.11ac. It's been over 500 days. I think another 200 days or so will be well worth the wait.
