There are many reasons.  One is priming the pump.  At some point in the
future applications are predicted to become so content rich (bloated)
that individual application processes will require more than 2GB of
address space.  Moving to 64 bit now gets everyone ready.

Another is the desire of developers to eventually dump the 32 bit x86
instruction set altogether.  Those who write the memory management code
disdain the segmented addressing scheme of x86.  x86-64 provides a much
flatter memory model which is easier to program.  Those who maintain
complete distros, such as Debian, would surely appreciate building
~30,000 binary packages instead of ~60,000, and tracking/fixing bugs in
only one of these instead of both, etc.

To name a few.
