There's too much "Dany in Westeros" symbolism for her not to make it there, imo. I think she'll especially get her shit together once she hears about "Aegon" wrecking shit. I think Tyrion played him into overexposing himself, and he'll likely be killed/defeated before Dany can save his ass. Dunno if I believe he'll take the throne so quickly but he'll certainly be a potent threat with the Lannisters in disarray and the Tyrells threatened on multiple fronts.
Of course I'm hoping for Stannis to come out on top in the Winterfell battle. I'm worried because nearly every theory/prediction says he'll win the battle, it's the most obvious and logical thing...which means Martin will find a way to throw a wrench in our carefully laid plans lol. But seriously, Stannis has every advantage right now: he has the high ground, he has Northern troops, he was able to defuse the traitors before they could attack, and the Manderlys will be on his side covertly. And he has some type of trick planned, perhaps with the ice lake. What could go wrong lol
