Is this the crap about the drunk Nazi soldier saying they decapitated him.
What of Mr. Immortal?
And (perhaps) Darwin?
EDIT: Whoops, someone mentioned Mr. Immortal.
Anyways, most Omega-level mutants have the potential to be immortal, as they exist as pure energy. Wolverine, last I checked, couldn't exist as pure 'healing' energy.
Though I wouldn't be surprised to see it happening in upcoming issues.
