Interesting case but this is not a question of electronics but of economics.
For any given technology one chooses to implement a machine in, there will
*always* be a technology faster, smaller, cooler or whatever.  The only 
"problem" with the technology is that it will always be unfavorably expensive
to built the entire machine out of-- but just a bit for cache will make
the budget if engineering promises large gains for small investment.
There will always be a way of making a cache memory for a system that 
will be faster than the main memory.  
		MOS -> TTL -> ECL -> GaAs -> Josephson -> ???

So the answer is no, they're will be cache until engineers don't want to
squeeze that last bit from the technology they are using.
