According to the site, "she did confirm to me that she would be returning in the role. Most likely. Practically 90% sure. And she nodded a lot too. I can't say, and neither could she say that it's definitely a done deal, and that the contracts have all been signed, with all the "i"s dotted and the "t"s crossed.
They added that there "a few details that are still being negotiated which she couldn't get into. But since she did tell me that the film starts shooting in April, it's highly unlikely that talks are going to suddenly and horribly fall apart at this point, and the producers have to scramble to find a replacement at the very last minute."
Stay tuned for possible confirmation that she will officially be back.
Hugh Jackman, Ian McKellen, Patrick Stewart, James McAvoy, Jennifer Lawrence, Michael Fassbender, Nicholas Hoult, Anna Paquin, Ellen Page, Shawn Ashmore and Peter Dinklage are already on board for the July 18, 2014 release.
