That's some lopsided armies right there. Since they made a point of showing Kevan Lannister exploding with with the rest of them, it seems likely to me Jaime will finally take his place as Lord of Casterly Rock, Warden of the West and commander of the Lannister armies. And I don't think it's a done deal he'll throw in with Cersei. He's seen her for what she is and Tyrion will no doubt reach out and try to get him to join Dany.
Even if Jaime stays with Cersei the battle should be easily won by Dany's coalition which is why Klaus is probably right regarding the Walkers destroying the Wall and heading South sooner rather than later.
The Crow's Eye will no doubt try something but they have done such a bad job building him up I wouldn't expect anything. He's been in what, a grand total of two scenes so far and is nothing like the menacing, mysterious creature from the books. At least he got a look in, Victarion was cut altogheter. Shame D&D. Shame. Shame.
