Warner Bros. has secured a deal with Danish toy company Lego, that will allow TT Games to keep developing Lego-games; all the way up to 2016. That gives TT at least six more years to interpret Star Wars, Batman, Indiana Jones and Harry Potter - and probably other new franchises they can get their hands on.
Didn't anyone tell them that the world ends in 2012? Get busy, TT Games! Anyway, the next Lego-game that will be released is Lego Harry Potter: Years 1-4 which is out in May; that's in good time before the apocalypse.
