Really it's a trivial thing and doesn't really matter. Why we discuss these things like they're going to be the reasons the movie does well or not baffles me. To echo the thoughts of AvBaur which I agree with, yes this is most likely an attempt to distance themselves from the previous film which almost everyone disliked and thought was a piece of shite. The fact that there is a profound effort to make second film more entertaining and more in tune with the Wolverine we know from the comics should be encouraging, everything else is immaterial and doesn't matter. As long as it's a good film I don't really give a rats ass.
