That has emerged from an online discussion at the INA Community site.
We presume that the game will be developed for AMD's ClawHammer processor rather than the McKinley, or for a 64-bit processor Via might get round to making.
While Intel made noises a few years back about a desktop Itanium machine, it could be a little while before that type of machine breaks into the wonderful world of gaming.
So we suppose that 64-bit UT2K3 will make its debut on the Hammer platform.
Here's the thread. µ
