Interesting thought but could play havok if there was a lazy dev that just relied on the fix speed of the console to do their timing for them. Not that I imagine any dev in this day and age would do something like that.
Added to that, it's not like that would really benefit MS or gamer's really. It isn't like it would be cheaper for MS. And it isn't as if dev's would be able to take advantage of any increase in capability as they still have to consider existing consoles.
I really wouldn't expect MS to do any changes with the X360 that weren't related solely to the UI, reliability or cost of the machine.
As to predicting the future. I'm currently not expecting anything new from anyone except possibly Nintendo before 2012 at the very very earliest. And most probably not for a few years after that.
And thus the only thing I can think of would be more programmable general purpose GPUs that are more like Larrabe.
Possibly with Sony/MS both looking at a CPU/GPU integrated on the same chip.

With the more complicated hardware, I don't think developers could code based on strict timings anyway. They would have to code to a best and worst case scenario between cache misses, memory vaguaries and multi-threading. With increasing the hardware performance a little, Microsoft may have to give their console a small clock bump anyway to control leakage (This was explained to me, so im not the source of this) and in the end all I was thinking was making a refresh which always gives the software running a best case scenario level of performance to keep games running a little smoother.
Beyond that, with a slim console one of my most wanted features would be the ability to form an ad-hoc local lan connection between two or more wireless equipped consoles so having a few more processor cycles could help here as well. Furthermore as the consoles are the local hosts in games it would help to improve performance for other consoles connected to the local host.
As for new consoles, between Microsoft and Sony we're seeing a proportion of the console market being locked into a particular brand of console by nothing more than peer pressure and staying with their friends. As the networks are not interoperatable it seems to me that the incentive is to release earlier to lock in people to a certain console and reap the network effects with people wanting/needing to buy a console that their friends own. In this case it matters even more than ever what consoles your friends have so an early start and lead becomes even more valuable. This is why I wonder if a late 2010 early 2011 start by Microsoft should be expected?
