Actually it is way more profitable to create console games than to create PC games: The console hardware is clearly defined, no surprises, no gazillion of configs and a wide performance range, and software piracy still is way way below what it is for PC software.
The ugly side of this is that many game developers primarily build their games for consoles and their limited controllers and storage devices, and usually the PC ports of these games suffer from that in exactly the areas of controller and savegame handling; something I have come to hate from bad experience.
Finally, Descent needs so many controls that imo it is not really suited for a gamepad (I have a PC gamepad, and D2X-XL supports it, and I find no way to control the ship with the gamepad as good as with a mouse or joystick and keyboard combo).
So I hope Descent 4 - should it ever become a reality - will at least get a solid PC port (probably with extended controller and i/o handling capabilities built right into it), or be a PC first game; but I am afraid it will not turn out that way (unless some rich guy wastes a few million on it for the heck of it w/o caring of any profits).
