re: Crackpot ASOIAF Theories SPOILERS

So, sadly it seems as if the trailer has confirmed that Aegon is completely out. I have to say this will be the biggest departure in the series so far, and I'm kinda pissed about it. Seems with both Euron and Aegon out of the picture, they've dumbed down the series to merely Dany vs Cersei. Was it that hard for the Hodors to keep up with the War of the Five Kings? I'm not sure how much of a part Euron has to play, what I am confident of is Aegon has gigantic one to play. Guess Sansa may enter the fray at one point by her and Littlefijger taking out the Freys (pun intended), but that's really it.
