I'm in the market to get a new 27" iMac. I would pick the stock version currently priced at $1,699. My question is, (and I know no one knows for sure), is there possibly going to be a refresh within the next two months, and if so, what are people expecting the update to be? I don't imagine they will change the form factor much at all. I've seen or heard Retina, but honestly, given the current resolution on an iMac, I see no reason to add "Retina" resolution. So throwing the possible Retina upgrade out the window, what exactly do you think an updated iMac would offer? If it's Retina only, I'm apt to go out tomorrow and buy the current 27" model. If we are talking about the inclusion of an SSD drive, USB 3, better graphics card, etc, then it may be worth sitting on the sidelines for a bit. Any thoughts and opinions are greatly appreciated!
