I wish people were a little more open-minded about consoles. I used to be a PC-only kind of guy with all the Quake mods and Deus Ex and all that jazz. Back then the attitude was consoles couldn't have deep games or console gamers didn't want them or something. Consoles don't suck anymore (although access to the PC mods would be awesome!). The games have gotten remarkably deep on consoles. But since they're aiming for a primarily PC-base and a hardcore market it's very hard to imagine the new PC game would be compromised in order to make it adaptable to the console.
Although I only played a couple hours of BG I can't imagine why it wouldn't fly on a controller. The direction pad could be set to 8 spells or items and R1/L1 could each open eight more (like in NWN). You could manually select targets or use keys to cycle through them. The FO3 interface on Xbox is just as elegant, powerful, and utilitarian as the FO1 interface on PC - you can simply do more things faster and the interface isn't dumbed down or simplified. So I think the assumption that multi-platform releases detract from computer games is faulty (with the obvious exception of Starcraft and a few others).
As a computing professional sitting at a desk for more hours every week and managing game DRM/settings isn't relaxing anymore. PC-only is a deal-breaker. I'm hoping System Shock, Thief, Deus Ex, Torment, and all the other classics get the same treatment.
