INTEL is SOL.
I don't know about 2010 and 32 cores, but in the distant future, I can see there being thousands of cores in a single computer. Each the size of a head of a pin. The future is never really clear, but your comment here was extremely short-sighted.
On current technology (the technology that's really carried us from the 1970's til now), it's rather unlikely.
The smallest process that's possible on silicon based material, such as SiGe, only would be able to function as semi-conductor down to a process of 5nm or so, given the size of the individual atoms, as well SNR considerations and such.
Beyond 45nm generation that is being worked on right now, you have an additional 6 generations, maybe 7, of progressively smaller processes; each following Moore's law at approximately 70% of the size of the smallest feature on the die from the previous generation. You will probably have a max number of 25 billion transistors for the same die area as on current chips. Given that currently, the average dual core chips have 200 mil transistors, give or take some; if you stipuate that the complexity of each core does not increase over time (which is extremely unlikely), you would have maximum of 250 cores that will be possible for each chip, if the die area were to remain the same as that of today.
So barring a new technology coming out of semiconductor matsci (which is entirely possible, semiconductor industry had surprised us before, just not on this scale), you will be looking at realistically a max of 100 core per processor, given that at least some increase in complexity in the cores will be very likely (used in such area as additional execution units, extension to ISA, etc, etc), or perhaps even less. A chip with thousands of cores at this point is nothing but a pipe dream, unless someone finds a material that would be able to replace silicon compounds entirely.
