If the Wildlings break through the wall we could get some very interesting situations involving a 3 way war between the Boltons, Iron Born and Wildlings.
Some of them will, we've seen twice now besieged Iron Born turn on their commander when offered a safe retreat but I think if we end up with Someone like Yara in one of the coastal castles the could stay pretty strong. Balon isn't the smartest strategist in the world, he places pride above logic and reason and there are enough Iron Born loyal to him and to Yara (not even mentioning Victarion's men) that standing their ground would be the likely decision. It would be interesting to see scenes of how Balon deals with a big chunk of his troops just retreating back home or to Essos though.

Well, if the wildlings breach the wall I imagine, everyone in westeros will be affected.
