We'll see. For that, ARM has to seriously crank up computational capacity.
Currently, a rule of thumb is that a single core ARM CPU gives you about
the computer power of a modern x86 core running at a quarter the clock
speed. All that crazy effort of massive caching, long pipelines, predictors
and so on _does_ pay off ;-)
Consider the "VMware Principle" - the idea that a huge percentage of
current company/corporate servers are running at a tiny fraction of
their CPU capacity.
Until recently it's been very difficult to get lower-powered
processor options in a server class board. IPMI, ILO, redundant power
supplies, watchdog capacity, etc, have always put you into premium
processors with their attendant power and cooling budgets.
I suspect that the new ARM server-class systems will fit VERY nicely
into that gap.

But
either way, Core i7s might be considered "classic" soon too, with
all the server manufacturers gearing up to produce ARM-based *servers*.
And I believe this will be a huge step toward better servers and
less power consumption!
