Bah...what are they thinking! Previews I have read kind of alluded to this though, saying that Issacc is more badass and is a necromorph killing machine etc.

The fist game was plenty action heavy in my opinion, especially if you played through it a second time on your completed save file, the necromorphs were much faster and there attacked more frequently. They should be focusing on more imaginative ways to scare the crap out of you.

We will have to wait and see, I will remain positive because the first game was so good.
