"X-Men Origins: Wolverine" is pretty much being ignored by both filmmakers...and I think he's more surprised that anything could take his mutation away. This Logan seems to be more haunted and beat down mentality than the one in "The Last Stand". A tired Logan, unless of course the Cure is something that is being "ignored"
Also we know from Magneto at the end of the film that maybe it didn't work.
I think it looks absolutely fantastic. Viper looks great, this is going to be awesome.
