Games based on the movie

[Saruman]

I know that there's 'The Two Towers', and that 'The Return of the King' will eventually come out, but will there be any more? Judging from what I've heard, the ROTK game will focus on Sam, Frodo and Gollum's journey, and TTT follows Aragorn, Legolas and Gimli, but will there be a game following Merry and Pippin's journey? And what about Gandalf? He does meet up with some of them from time to time, but there are a lot of exciting parts where he does things like battling the Balrog and so on.

Never mind - I found out that there wil be three games.
ROTK will follow both Sam and Frodo's adventure and Aragorn, Legolas and Gimli's adventure.
The third game will be called 'The Lord of the Rings: Trilogy'. Judging by the title, we can assume that it will be based on all three.

Merry and Pippin will have a part. Pippin will help defend Minas Tirith, and Merry can take on the Witch-king on the Pelennor Fields.
