When is the new iMac to be expected?

I've heard various rumours for a while now. Originally, rumours spread that there would be a new iMac announced in September 2012, alongside the iPhone 5 - but that didn't happen. Now, rumours are spreading that the new iMac is to be expected in October 2012 - it's mid-October now, and I haven't heard anything official.

I've been looking to buy an iMac ever since the current model was released, but never had the money (as I'd like to use it for my graphic design work). Now I have the money, I'd like to get the new iMac when it arrives - but I don't know when it is! :/

I don't want to buy the current iMac model, and then a month or two the newer model comes out. That would suck. And that's happened to me before with my original iPad. I bought my iPad, then a month later the iPad 2 was released! And at a lower price! I was gutted.

But anyway, does anyone have any clue as to when the new iMac is to be released?

From what I'm seeing… Apple indicates it will be between October and the end of the year. That's 90 days of waiting. They want to create "hunger" for their new products, so the longer they keep you waiting, the more you want the newest Apple iMac. Here's a link that should help.

It could happen later this year or it could happen at WWDC 13 which may be in june of next year.
