Speculation from the net: The rogue cut will play out like this…
I kinda believe this , b/c if you watch the 1st trailer there is a snippet of a scene where old Magnus/Iceman are carrying an unconscious Rogue through a building…
SPOILERS for people who don’t want to know what will presumably be included in the Rogue Cut:
[details=Spoiler]Due to Rogue being included, the emphasis on Mystique’s blood being the key to the Sentinel’s powers is played down, so I’m assuming the intro (with the Xavier voiceover explained the Mystique thing) will be tweaked or removed. (I’ll explain why below).
When Wolverine sees Stryker and slashes Kitty to the point where she’s bleeding out, that’s where Rogue’s scenes come into play.
Rogue’s inclusion actually changes a lot of scenes in last third of the film, though the ending is the same.
When Magneto, Iceman, and Xavier have that talk about Kitty being too injured, in the “Rogue Cut”, that’s when they decide to rescue Rogue, as her powers allow her to do Kitty’s job.
Rogue is being held in the X-Mansion, which has been converted into a Trask Laboratory. They are experimenting on her by taking her powers and injecting them into the Nimrod Sentinels (which explains how they absorbed Iceman and Colossus’ powers in the beginning of the film). That’s why the Sentinels are pretty much indestructible, because they can just absorb a mutant’s powers and then be immune to the effects. I’m assuming Mystique’s blood just allowed the Sentinels to “shapeshift” through powers permanently, to adapt to an enemy.
A bit of the rescue sequence was seen in the first trailer, but pretty much Xavier flies the X-Jet, Magneto and Iceman rescue Rogue, but Iceman is killed in the process.
I’m assuming around the same time, this is where 70’s Mystique’s trek in the Mansion is happening, where she runs into Wolverine and Beast (seen a bit in the trailer - the whole Wolverine’s speech to Mystique about being"badass but crazy" Mystique’s all “tell me how you really feel”).
The Mansion burns down as Magneto, Rogue, and Xavier escape back to the Temple. Rogue takes over for an almost dead Kitty. Also, this was the reason why the Sentinels were able to the find the X-men at the end of the film. They followed them as they escaped the mansion.
It’s not been clarified if Kitty dies or just stays heavily injured, but based on the b-roll footage, Kitty’s foothold on keeping 70’s Wolverine stable suddenly gets weaker, since in the b-roll footage, Wolverine wakes up in the mansion saying “Rogue!”, knowing that she’s taken over. Beast then comes in to tell him Mystique’s gone.
I’m assuming this leads into the Presidential address that takes up the last bit of the film.
The rest of the movie pretty much plays the same.[/details]
