According to TotalVideoGames.com, Eidos has confirmed that E3 2005 will be where the next installment of the Tomb Raider series will be "demonstrated".

We hope that by "demonstrated", they are referring to the first actual live gameplay they will show, but that they will indeed show us some concept art or screenshots beforehand.

Speculation as to the release date is now up in the air in many peoples minds. The game has been said to be released Summer 2005. If it is demostrated for the first time at E3, which happens in early to mid-May, one would think that the game would likely be pushed to a later date of November-December. But, as was said, this is all speculation.
