I'll explain the motivation for 64 bit only DMD binaries:

1. It cuts the testing time in half. This is a significant deal for me, as 
adding another hour to the test cycle slows things down a lot.

2. It speeds downloading the dmd package.

The only reason to have a 32 bit binary is if there are x86 Macs 10.5 or later 
that are incapable of running 64 bit code.
