If anybody would be kind enough as to let me know what the preview might spoil. Also, could somebody tell me about non-spoiler info such as new factions/features/guns?

well on the x-play site the show will cover

1. The Story of Fallout: New Vegas
We'll start off with Obsidian Sr. Designer Chris Avellone and a look at the storyline of Fallout: New Vegas, which takes place 4 years after the events of Fallout 3.

2.The Characters of Fallout: New Vegas
After setting the stage with the storyline, we'll dig deeper into the humans, robots, and mutant monstrosities that populate Fallout: New Vegas' Fortune City.

3.The Weapons of Fallout: New Vegas
Project Director Josh Sawyer explains how Fallout: New Vegas continues and expands upon the franchise tradition of using anything and everything to wreak bloody havoc on the undead.

4. The Art of the Apocalypse
It ain't easy creating a zombie apocalypse, and we'll talk with lead artist Joe Sanabria on the ideas and inspirations behind the Vegas-like Fortune City.

5.Fallout: New Vegas New Features
Fallout: New Vegas is not just Fallout 3 reskinned, and we'll take a look at all the changes, from factions, traits, and hunting, to even the way you aim your gun.

6.Sin City Destroyed
We'll take a tour of the huge open-world setting of Fallout: New Vegas' Fortune City, where the environments range from desolate wasteland to glitzy New Vegas Strip.

7.X-Play Exclusive: The White Glove Society Mission
In a franchise full of disturbing missions, The White Glove Society Mission somehow manages to be Fallout's most disturbing yet, and we'll have an exclusive look.

It would spoil what the inside of the Ultra Luxe looks like and what happens if you take the evil side in a side quest.

Sounds like your answering questions about a merged Dead Rising 2 and Fallout New Vegas game.

Wow....I haven't been on these forums in ages.

Fortune City? Undead? What in the hell? They got Dead Rising 2 and New Vegas mixed up!

Did you really expect anything from G4 beyond half-assed?
