Word on the wires at the moment suggest Canon are preparing to launch the 20D replacement at the end of February with in store dates no more than a few weeks later. This would put it right at the end of the usual Canon product lifespan window. The current model is such an accomplished all rounder it's easy to forget it's been out a while now. Will be interesting to see what it will be specced at - even by the usual forum rumour mills everyone is being especially tight lipped about this. Will be difficult to see how they will place it as they would have at least have to match the Nikon D200 but that would subsequently blur the lines a little with their own 5D model. I guess time will tell.
