So is Tycho's elite ability essentially the Grit keyword or am I missing something? And, if it is, that seems a little weird/disappointing. Right?

I can't find it now, of course, but wasn't there talk of grit being this? Basically you can't be engaged-in-place? Or am I making this whole thing up?
If that's not what grit is then Tycho's ability is cool and now I'm wondering what grit does. The other wave 2 keywords are intel (?) and rogue (you may move and attack when activated ).
