I think that reimplementing/dumping Microsoft .NET-based toolset and overhauling UI aimed for PC users (F1-12 quickslots, mouse) is too much of an effort.
Plus, NWN2 is targeted towards PC gamers.
But, anyway, why should you have a 'nice' rig to run NWN2? By the time NWN2 is out you will be able to get a decent videocard cheaper, you don't have to have the latest hardware if resolution under 1600x1200 doesn't drive you crazy.
