American Physical Society started a new journal - Physical Review X. It's somehow analogous to the New Journal of Physics: an online-only open-access journal, covering all branches of physics. As far as I understand, there will be no page limit for articles, and you'll have to pay $1500 to publish there (you also retain copyright to your articles due to open-access).
The first call for papers opens in March 2011, so hurry up! :-)
