To jump with the default key assignment yes, you have to move your right thumb off the analogue stick to press triangle. Or you can assign jump to clicking the analogue stick. Your index finger is always on the right hand triggers for spells or shout.

Timing and aiming spells is pretty precise in Skyrim. Saying a word or making a gesture would not work with how the game works currently. 1 pixel off or a fraction too late and your spell might hit a nearby object instead of the enemy.

It would be cool at first but theres no way you would drop the controller to dual cast heal or a fireball in the middle of a fight leaving your charactor immobile.

As always with this kind of idea, it sound cool in concept, but is boring and convoluted in practice. Motion control, as they are now, are not made for this.

rather not every have kinect games, honestly hybrid games are just gimmicks, kinect games are terrible
honestly the problems are numerous, however, halo wars kinect would be possible

Skyrim + Kinect will just mean more glitches and bugs.

Instead of talking it up all the time, why doesn't he make a game for it?

CliffyB is a great designer and some of these ideas are pretty cool. But since a ton of 360 owners don't own Kinect hybrid games still have to be made for 360 with some features tacked on for Kinect. You can't make a true hybrid experiance because you'd be alienating your base. I think with the Nex-Box this will change because every Xbox purchase will have Kinect and then every single game can feature Kinect based controls.

But right now it just isn't feasable to make all the games with Kinect capabilities its a waste of time and resources and likely won't improve the software much. Also while I like the idea of playing Skyrim with hybrid controls I would get a little tired of playing with my controller then suddenly having to cast a spell or use some other device with motion controls. Mixing them up would get tiring and annoying.

I think voice controls could work amazing with the classic controller as we saw UbiSoft do with EndWar maybe with slightly more classic controls then EndWar but they have the right idea. Mixing in motion controls that involve taking your hands off the controller might not be the best idea. Maybe leaning forward and from side to side could be implemented in hybrid games that would work very good. But I can't see swinging your arms while trying to play a game with a classic controller.

You don't need Kinect for voice commands...just sayin'

Could be cool but I'd rather have Skyrim with Wiimote/Move controls.

Fable the journey is NOT on-rails, Molynuex said it like a trillion times after the E3 expo. It seems that demo really killed the game in people's minds as being some kind of wishy-washy casual on-rails crap. But its not.
