NBC Universal president Ron Meyer says there may be a sequel to Snow White and the Hunstman, but that it will likely follow the Huntsman character. One can only assume that such a sequel would then not include the titular Snow White character, played by Kristen Stewart. From THR:

Meyer said that while the upcoming Snow White and the Huntsman doesn’t appear to lend itself to a sequel, Universal thinks it can do more movies based on the character of the Huntsman (Chris Hemsworth) if it is successful.
