It's not going to happen on any hardware.
It can only happen if the hardware architecture has a major change (generally a
different generation of processor core).
And it is not guaranteed that the next update in hardware architecture would
give a similar result. In the next update, Junior could be 3 times faster and
Gandalf only twice faster (maybe due to simpler code that puts less stress on
the branch prediction system of the P4 for example, who knows).
In any case, on a given processor, doubling the speed is the same as having time
controls twice longer.
