A discrepancy between two versions of the official Deus Ex 3 teaser trailer could have let slip the biggest reveal to date on the sequel.

In one version of the trailer, a scene has had the date "2027" removed, while it remains in the same scene in a second version.

The evidence is on display in the two screenshots you can see on this page, which were taken by PC Zone magazine's editor who noticed the discrepancy while gobbling down every Deus Ex 3 info morsel currently available.

It's led to us speculating that the sequel actually acts as a prequel and could well be set prior to the original Deus Ex (which was set in the 2050s. Invisible War was set 20 years on from the first game).

Did Eidos spot the slip and move quickly to eradicate evidence to protect a plot secret? Could be.

So far the publisher's said very little about Deus Ex 3.

The only real juicy bits are the fact that it's using the new generation of the Tomb Raider engine and that a replayability angle is a major goal with the storyline.

Oh, and that it's years off, with the boss of Eidos Montreal saying the team wants to have a minimum of 24 months to complete the project.
