If Marsden is in this film I expect Singer will focus on him more while keeping Logan in the background. I don't put it past Singer to do that and I don't think Hugh would actually mind because even side bits of Logan will be just fine. I still think this will be Cyclops film if/when Marsden is announced with Paquin, McKellen, Stewart and Fassbender close runner ups. If Famke is announced then it may change things. Either way this movie does seem to be focusing more on the original cast than the FC cast.
