With upfronts in full swing, NBC is still riding the publicity high from its presentation this morning. Releasing plenty of previews for their new fall series, NBC is hoping for a big year compared to a rocky 2010-11. Now, they’ve unveiled the full trailers for their upcoming new fall line up, while also setting a date for the anticipated sci-fi thriller Revolution and the next season of their hit reality series The Voice.

The biggest news in fact comes from the firs two premiere dates of the season. NBC has revealed that The Voice will debut on Monday September 10th, and will be followed by the series premiere of J.J. Abrams and Eric Kripke’s Revolution.

Adding to the intrigue, NBC President Bob Greenblatt says the plan is during the 2012 London Olympics, the network will be previewing different pilots in 30 minute intervals. This means that comedies will get full early premieres, while dramas will only get half-way through. Matthew Perry’s Go On is said to be the earliest front runner for one of the previews, while more will be revealed at a later date.

Below, we have the trailers for the six new series debuting this fall for the network, which was only expanded upon by the massive 27 videos of all 11 new series from yesterday:
