Picture:

Actor:
Daniel Day Lewis will win. Hugh Jackman and Bradley Cooper are my close seconds. I will be amazed if Lewis doesn't take this category.
Actress:
One old, one young; not enough to win the award. Jennifer Lawrence was great and Jessica Chastain will most likely get the Oscar.
Director:
Without Ben Affleck getting nominated (wow!) I would resort to previous winner for the Fighter, David Russell. Steven Spielberg will most likely win for Lincoln.
Supporting Actor:
Robert Dinero was excellent in Silver Linings, but Christoph Waltz was amazing in Django and should win. Alan Arkin may win for Argo.
Supporting Actress:
Anne Hathaway was exquisite in Les Mis, but Helen Hunt may come out and take the win for The Sessions.
Winning an Oscar doesn't make a film better or a performance more outstanding. This is the product of the masses. Either way I will be watching with baited breath!
