There have been numerous other posts of late with this same question. You can expect a barrage of remarks that may make you feel a bit incompetent. I've been in the waiting game as well and will continue to do just that. No one knows. MacRumors.com will give you hints of when to buy. Most will agree that if you need one now, buy it. Others will say, if it's so near another cycle of revisions, hold off. Someone else might ask what you may use the iMac for and, if just using it for minimal tasks such as browing, email, etc., why wait for something better when the present iMac will do you just fine. I myself don't like buying something that is replaced the next week or month with something better. That's my nature. But it can be brutal. I may even give in this next week or so and go for an Apple Refurb. Photoshop is about the most I do on my desk, so in actuality, my Powerbook G4 I just sold, did just fine with that. I am waiting for the LED display, which may come this time or not. No help to you with these words, but I don't think anyone can tell you any more.
