I know what you mean, I've been fooled by fan trailers before.
The movie is currently filming. I'm sure, once they get some stuff done and ready, they'll cut a teaser trailer. It will have some live action in it, not just paintings. (really good paintings, but those were paintings) The person who created it took credit in under the video and definitely deserves an A+ for effort. It's really nicely done.
I'm definitely looking forward to this movie. I enjoyed the first film a lot and I think Hugh Jackman is awesome as Wolverine. Counting his cameo in X-Men: First Class, he'll have played a superhero in an unprecedented 6 films with this new one. He officially took the record with said cameo. (I know Christopher Reeve did 4 Superman movies, I don't think anyone else has even done that many)
