If you are itching to play Resistance 3 like I am, you cab try it out a bit early. With the blu ray release of the movie Battle Los Angeles you can get your hands on the demo for Resistance 3. There has already been a little cross promotion between the 2 titles as a Resistance 3 billboard appeared in the movie.
You can get the DVD Demo combo when it releases on June 14th. Resistance 3 releases September 6th exclusively for the Playstation 3.
