For as many times as I say it, I get attacked by those who feel the rumors that tell them what they want to hear are more credible than the fact that there is no news from Apple.
And this is your most baffling point. I don't understand why you always go back to it. There is never any news from Apple. If you were in the market for a phone, would you buy an iPhone today?
Here's what we currently have:
2012 iMacs: Credible analyst reports from people that have been accurate in the past, Apple PR correction excluding iMac from the 2013 list, and no news.
2013 iMacs: Baseless speculation and no news.
Why should baseless speculation and credible analyst reports be given equal weight? Certainly it's possible that either outcome could be correct, but the fact that there are two possibilities does not automatically imply that they have an equal probability. Most of us here are taking what you might call a calculated risk on the probability of the credible reports being correct being much higher than the probability of the baseless speculation being correct.
