I don't want to see an iMac upgrade at WWDC. Here's why: Intel says that Broadwell chips will be released late this year. IF Apple decides to release a Haswell refresh iMac at WWDC, they are surely not going to refresh the iMac again a couple months later when Broadwell chips are released. IF there is a Haswell refresh iMac, I would only purchase it if there is an option for a 4K display and Thunderbolt 2 capabilities. I think the Broadwell refresh will probably be a major update, possibly a new design, 4K availability and Thunderbolt 2. Any thoughts??
