All charcters who died during Krakoa are clones, imo. Storm is the only main X-Men left.
To me this was confirmed after the **** show of having 2 Lauras at the same time. Maybe the ones that come from that place Wanda created are actually the original characters coming back into a new body, but the ones that come from the back ups are definitely clones, maybe they have souls of themselves that make them unique individuals, but they aren't the actual characters. Cyclops died in the Mother Mold in HoX/PoX and we have been reading about various of his clones, for example.
Also, it makes no sense Cyclops haven't chose to fix his powers in the resurrection process, everytime he loses his visor in battle he becomes a liability to his team and that would be reason enough for him to fix his powers.
