The Gravis Xterminator gamepads are pretty close to the DC controllers (which I like far better than the N64 controllers, which are just goofy), though the analog sticks aren't as good, plus you've got two extra triggers, a hat stick, and a throttle.
All are programmable. Of course you don't get vibration, but for me, it's an over-rated gimmick (and really only appropriate in certain games anyway).
Why would you want it? Well certain games are a lot more fun using that as a controller than a keyboard and mouse. About the only games I actually use keys/mouse for are post-Quake FPS games, and maybe Thief.
If I ever get "Typing of the Dead" then that would be another game I'd use the keyboard for. ; )
To the initial poster, nope, we haven't seen anything yet and no plans by LEC to port JK/MotS to any other platform has been announced (they cancelled the Mac JK back in '97, remember?).
I think it's probably a safe bet that neither game will get ported to the PSX, though an Xbox or PS2 port might be interesting. I'd love to see a DC port (if they can do UT, Quake3, KISS SC:TNC, and Rogue Spear, they can do JK), but it appears as if LEC has stopped supporting that platform (with the cancellation of Super Bombad Racing DC).
