CBS has announced the new houseguests for season 15.

TV Guide reports that the new season will be hosted by Julie Chen and will feature some new twists.  Each week, the contestants will nominate three players to be eliminated instead of two. Also, viewers will be able to vote for the house MVP, who will have special powers for the week.  Both of these changes will be in effect when the season premieres on Wednesday.

Watch the premiere on CBS this Wednesday at 8/7c.
