Ok, so I thought I'd make some last minute guesses on these teasers, just to see how right or wrong I wind up being.
Father and son encounter something strange in the wind.
I still think this is referring to Bigby and Mr. North. Possibly in regards to something else that is coming, or possibly it's an ambigious way of telling us that we are finally going to see them meet and it's gonna be a trippy reunion. Still, there is the strong possibility that this could also refer to Bigby and the Seventh Cub.
A bunch of tattle-tales
Either this refers to the cubs or to the inhabitants of The Farm. It might also refer to the Mouse Police. Either way you slice it, I think it involves Bigby's appearance. If it's the Cubs, maybe the tell Rose or Snow. If it's the Farm Dwellers, it's just them sounding the general alert that Bigby is where he shouldn't be. If it's the Mouse Police, they tell Prince Charming. Actually, even though the cubs are the running bet, I think the Mouse Police have a strong underdog possibility here.
Got him on the rebound.
Hmmm. Could be in reference to Beauty, Beast and Charming. Or possibly something the whole menagerie of Blue and Ride. For some reason I got this sneaking suspicion that Rose has some designs on Blue. Or this might have something to do with Cinderella. We know from solicits she's going to be performing missions in the Cloud Kingdom and later Smalltown. Maybe this is how she gets ahold of Jack's magic beans (heh heh). Or maybe it means Humpty-Dumpty

.
Geez, is he whipped
You got to love ambiguous semantics. Could refer to whipped as in the docile sense, or in the physically dominated sense. Don't even know. For some reason, I think it might involve the dominated meaning rather than the romantic one. Or maybe somebody actually gets physically whipped with whips. Heh, heh, part of the whole "catching them on the rebound" thing.
Whisky and lots of it
I think this either refers to Frankenstein's head or the Forsworn Knight. Possibly something in regards to Bigby, but I don't think so. I lean more towards the first too. We know drink causes the Knight to speak and prophesize. We also know that Frank likes to drink. In either case, Bufkin was the guilty party. I'm leaning on the Knight getting some more screentime here, it seems like the time for it.
Say good-bye to meat on a stick
Either no more Colin in Snows dreams, or maybe just a really glib jibe on Mowgli not having to live in the wild anymore (we see him eating meat on a skewer in the preview

).
Bored
Who knows. Riding Hood maybe? North? The Cubs? Thrushbeard for not getting enough screentime? Have to see.
Departures x 3 (or should I say x 6?).
Well, this is a tummy-teaser. A very obvious guess is the Cubs. However, I don't think so. I'm thinking various people are going to be moving to where they need to be for #50 and the coming storylines. I think some of them will be obvious, the others more offscreen (like Blues departure was). Cinderella is one of the departed, I think. So, the other five are a mystery.
Uh-oh, I guess he couldn't find him after all.
Mowgli finds out that he really has been on a goosechase all this time, because Bigby is either on the Farm or almost there. Or perhaps this is more subtle and somebody is looking for somebody else in the story.
Signal(s) in the wind.
This is where I get my idea that the final panel in the preview is an indication that Bigby is coming and North knows it. Or, maybe it's something more.
Nothing bad is coming (but that might depend on your definition of bad).
I'm really up for believing this just means that Bigby is finally going to reappear, and about damn time. There might be something more to it, but I don't care at this point.
Ok, now we just have to wait and see how totally wrong I was
