Finally at a computer, I can explain.

Firstly, you cannot blame Origins for screwing with continuity as established in First Class. If anything, you can complain about Fist Class screwing with the continuity of Origins. So this gets rid of the Xavier and Frost argument.

So, Cylops' blast, I don't recall anyone stating it's a heat blast and it clearly works as a concussive force both when Scott uses it and when Deadpool does so. We do see Logan's claws heating up from the blast, but it only happens after some time. I'd say this is the effect of friction (rub your hands together, you'll see they warm up, even though only kinetic force is applied).

COming back to First Class. We do not see 2 Emma's, we see Emma Frost and an unknown girl with diamond skin. Well, it's not unknown for 2 mutants to have the same mutation.

And Xavier. I admit, the filmmakers did screw up here. It's not a big problem in Wolverine Origins, as prof. X only appears for a moment, but comparing X2 and Fist Class it's a serious screw up. Or at least a serious retcon. Still, it's a problem with First Class, not with Origins.
