I didn’t see this mentioned anywhere so I thought I’d share.
It looks like it could be a preview for this Friday’s episode or it could be another generic promo. It has clips I haven’t seen elsewhere. I apologize if I am the last one discovering this.
I can´t see it 
It’s the same one they posted on FB last week. We’ve seen it. But thanks for sharing and letting us know. 
It definitely has a scene from this week’s episode I think. If I’m not mistaken the “boat” scene with Lion-O steering might be because this week is supposed to have fish men pirates. And notice Tygra has his armor in that scene so maybe we’ll finally see where he gets it.
The youtube video is out of sync, but the one on facebook isn’t. If you’re going to watch it, watch the FB one: http://www.facebook.com/video/video.php?v=792156919047#!/video/video.php?v=792156919047
Wow, gotta say, that was good. Though I doubt that’s all one ep. Just too much going on it that trailer for a 30 minute show. At least I hope so, if eps are that rushed then I’ll be pretty upset. Also gotta say, I find it funny that Lion-O and Tygra get armor but not Cheetara. Kinda odd.
I think that armor would just slow her down.
Oh yeah, her super speed and agility slipped my mind for a sec. That does make sense.
It’s definately not all from one episode. Most of it is from the premiere, though there are some scenes (the boat, the twins, mumm’ra in ever-living form) that aren’t.
