Honestly I can't say anything about timing as a simply don't know! However the products Apple needs are either on the market now or are coming soon. So I don't think an overhaul is that far off.
I do mostly database OCR and voice recognition work, very little video, no gaming.
I hate a slow machine and generally upgrade every 3-4 years.
It is nice to be able to do that.
I've been looking at the refurb 27" i7 units- in particular the mid 09 model. I don't feel I need the extra graphics hp for what I do.
Honestly a refurb 2009 model isn't much of a step up over a 3 to 4 year old model.
My specific questions are:
when the upgraded imacs are announced do you think they will be further discounts on the older models?
Well some stock does get sent to the refurb store at lower prices.
Would the SB upgrades be worth waiting for even for the i3/i5 models?
That is a very good question. If Apple tries to bone us with a SB processor and no discrete GPU then no they won't be worth waiting for.
many thanks for your advice

As a side note with respect to the need for attention to the GPU in your future machine I think you discount the need for a good GPU to much. In a modern machine a good GPU goes a long way to making the machine feel snappy, especially a machine with a lot of pixels like the 27" model. Beyond that you need to know about GPU acceleration in WebKit and the use of OpenCL by developers. Unless you have very specific uses where you are absolutely sure you will never be running future versions of Mac OS, WebKit or other system software I'd strongly recommend more GPU horse power than Sandy Bridge provides. Especially if you intend to keep the machine for 4 or more years as your primary user machine.
You might see this as a none issue for you, that is you have yourself convinced a good GPU isn't needed. You may very well be right today or based on past experience, just realize that GPU's are becoming more important to overall system performance. Even things like Safari are getting GPU acceleration. Further it isn't always easy to determine if software you will be using in the next 4 years will make use of OpenCL. It may pay to research your current software suite and find out which vendors will be using GPU acceleration in the future or for that matter already are. If you do go the used/refurb route I'd go so far as to say a good GPU is even more important as the CPU is already dated.
