Looks like Fallout fans were able to ask the developer at Obsidian questions related to Fallout: New Vegas and as you expected the questions they picked to answer were very insightful;

Will we be able to level past 20? Or 30?
From Justin via Facebook

JS: Our level cap is 30.

...

Will each faction have a radio station?
From @hawker101 via Twitter

JS: Not every faction has a radio station, but I hope people are happy with the radio stations, DJs, and music selection we have.

Will there be any sort of party involved? A few companions to tag along?
From Rui via Facebook

JS: Yes. The player may have one humanoid and one non-humanoid companion at any given time.
