On paper, the only confirmed character for Star Wars Episode 7 is R2-D2, though it is generally accepted that Mark Hamill, Carrie Fisher and Harrison Ford will appear as Luke, Leia and Han in some form. All three stars of the original have spoken publically about their desire to return and it's likely that, had negotiations broke down, at least one of the three would have publically distanced themselves from the project.
