DREDD 3D will use the Scope-on-flat format
Dredd 3D is expected to be released in September (UK and USA), October (Western Europe), and November (Germany). Karl Urban takes over the role of Sly Stallone in the original version of Dredd for the 2012 stereoscopic version.
The just released trailer visible here under reveals that the movie will use the same 'scope on flat' trick used by Disney on G-Force: if you look well at 00:45 to 00:50 in the trailer here under, you will see blood projection juming in your face and trespassing the lower edge of the frame, invading the black band under the movie. This is possible because Lionsgate is requesting the projectionists to use a wider masking than usual. The net effect is an increased presence of the action in the 'negative parallax space' (read 'in your face').
The new trailer (in 2D but in 'Scope on flat' mode)
The first trailer is still visible on Youtube (in 2D too).
The image here under shows clearly in-yout-face projections going out of the movie frame.

The video here under gives a detailed explanation of the Scope-on-Flat technique that was used for G-Force in 2009. The 9 minutes video is intended for projectionists and wad made by CineTechGeek.
The DREDD Official Storyline
The future America is an irradiated waste land. On its East Coast, running from Boston to Washington DC, lies Mega City One- a vast, violent metropolis where criminals rule the chaotic streets. The only force of order lies with the urban cops called "Judges" who possess the combined powers of judge, jury and instant executioner. Known and feared throughout the city, Dredd (Karl Urban) is the ultimate Judge, challenged with ridding the city of its latest scourge - a dangerous drug epidemic that has users of "Slo-Mo" experiencing reality at a fraction of its normal speed.
During a routine day on the job, Dredd is assigned to train and evaluate Cassandra Anderson (Olivia Thirlby), a rookie with powerful psychic abilities thanks to a genetic mutation. A heinous crime calls them to a neighborhood where fellow Judges rarely dare to venture- a 200 story vertical slum controlled by prostitute turned drug lord Ma-Ma (Lena Headey) and her ruthless clan. When they capture one of the clan's inner circle, Ma-Ma overtakes the compound's control center and wages a dirty, vicious war against the Judges that proves she will stop at nothing to protect her empire. With the body count climbing and no way out, Dredd and Anderson must confront the odds and engage in the relentless battle for their survival.
