I saw a comment from the game's writer that they're probably done with Chell. He said something along the lines of, "I think she's been through enough." However, he didn't rule out the possibilty of a Portal 3.Assaultman67 wrote:I think the ending provides a really great feeling of redemption from the hell of aperture laboratories.
But you know there will probably be a portal 3 ... so valve will probably nullify this excellent ending for a series ... meh . I guess they did leave "holes" for a new portal. Such as the mystery of chell's parents.
I agree with him. Portal 2 had such a good bittersweet ending. It would seem a shame to retcon or nullify that for the sake of a sequel.
