Detective Buck Tooth Ausir has alerted me to say this;
As I managed to find out, Plastic Wax, an animation company that created cinematics for such games as BioShock, Borderlands and many others, has also been contracted by Bethesda to make ones for Fallout: New Vegas. Hopefully, it won't be just trailers (although I'd love to see something on the level of Fallout 3's Prepare for the Future), but things like intro and outro cinematics as well.
If you click on their link you can see the games they made cinematics for which is a lot but I don't remeber any of them standing out as good.
