The release date for Blizzard's Diablo 3 is quickly approaching, and the company has been revealing slivers of information as the launch grows near. Recently, fans caught a glimpse of what to expect from some of the character classes, including Barbarian, Demon Hunter, Witch Doctor and Monk. The official television commercial for the highly anticipated game has finally made its way to the Internet, heightening excitement for the May 15th launch.

The TV spot originally aired on Sunday, April 29th, approaching the two week mark before the game's release. Fans are now able to see new cinematic footage from the game that hasn't been previously revealed. The unseen content was broadcast during Family Guy around 9 p.m on Fox.

With a menacing and thundering soundtrack introducing the 30-second snippet, viewers see various pieces of footage blended together in a cinematic fashion. As characters, spells, and creatures are revealed, the backdrop music begins to thump and pulsate, alluring viewers.

There isn't much gameplay footage, as the trailer emphasizes the cut scenes, but fans do see Leah screaming right before the video ends.

The words Evil Is Back are displayed towards the end of the teaser trailer, just before the clip's conclusion. Although the video is only 30 seconds long, the footage can give players some insight as to what the graphics will be like, the general art direction Blizzard has pursued, and where the storyline may venture.

The RPG dungeon-crawler phenomenon is expected to sell five million copies in its first year, Cowen & Company analyst Doug Creutz told Lifetime sales may also receive a significant boost if Blizzard releases the rumored console edition.

At the end of February, the gaming company made the first 20 minutes of Diablo 3 gameplay available online, and has since dropped further hints about what the next installment will entail. In the Developer Diary video, Lead Software Engineer Jason Regier said that the upcoming Diablo will feature a total revamp.

We completely overhauled the way that we author all of the skills, he said in the video. That meant that we pretty much started over on everything and redid it all from scratch.
