Enders Game (Spoiler warning!!!!!!!)

wow, i have to say i did not see that coming. i was getting towards the end an was like, well whens the battle gonna happen? then i come to find out, it had been happening all along. did anyone else see this coming? its kinda wrong they make ender stay up in space, but i suppose its for his own good. what are some of y'alls thoughts on this?
