The problem is that both men refuse to go outside prepared lines. The result will be draw after draw unless they change that thought process.
It is about time that they started 'playing' chess. There is more to it than just memorizing lines. Both men are at the world championship. Who cares about the past, who cares about ratings, who cares about studying the opponent.
Just start playing chess. Wing it and see what happens.
You don't know what you are talking about. In game 1 Carlsen avoided absolutely all theory, and game 2 had quite a bit of 'playing' chess in it too. Anand needs to stop equalizing positions where he has chances to play for an advantage (no matter how small the advantage is), as he did in the first game with Nd5 (forces a draw) and in the second game with Qxd5 (enters an equal ending).
The problem with this is that Anand doesn't need to win. He can draw every game and go to the tiebreak.

At this level of play, anyone winging it would be a fool. Maybe they are trying to take the measure of each other before the sparks fly. Some of the comments here strain credibility. These guys are not patzers and they don't wing it!
