UK based Eidos has been in financial trouble for a while now and today the publisher announced even more bad news as they have cut their revenue estimates for the full fiscal year due to disappointing US sales of Tomb Raider Underworld. Eidos said in a statement that while the game has sold well in Europe, the US sales have not been so lucky, saying, "In a difficult North American economy we have seen retailers restricting inventory levels and triple-A products being price discounted above our expectation."

As a result Tomb Raider Underworld is now estimated to have sold 1.5 million units world wide by the end of 2008, below Eidos' expectations. The company is now saying its full year revenue will be between 160 million-180 million pounds, below their previous estimate of between 180 million and 200 million pounds. Of course, late last year rumors were that Eidos was being considered for acquisition by several different parties.
