Like said, I haven't read the literature myself yet my friend just said it would cover most of the plotholes, what I know for sure, the books explain why the Ceph aren't ice based anymore, short version:
Their ice form was highly impractical for a large scale earth invasion so they redesigned themselves, from the Crysis Wiki:
The aliens in Crysis 2, which still relate to the aliens from the original games, have adapted along with the humans in order to dominate the intense warzones of Earth, going so far as to mimic their foes and commence an extreme overhaul of their technology. They have replaced their hovering Trooper automatons with trained Alien warriors in the flesh, equipped with minimalized, 7-foot high humanoid on-foot Exosuits that grant them incredible strength, speed and agility, making them more lethal than ever before.
More detailed info is in the books.
