Well, as 64-bit architectures become more widespread, using a
VM that's optimized for 64-bit is likely to be more efficient than
using one that relies on the backward compatibility with 32-bit.

Read e.g. "HiPE on AMD64"


Otherwise, enabling a much larger address space /is/ by far the
most compelling argument for 64-bit Erlang.
