Mortal Kombat 9 has a new feature article in the latest Playstation Magazine. It's a good overview if you haven't been keeping up with the game since E3 but doesn't contain much that hasn't already been made public.
This article is the basis for a lot of jubilation around the interwebs currently as it mentions a bunch of characters that have not been confirmed previously (Cyrax, Sonya, Kano, Liu Kang, Kitana, Smoke and Jax), but that list of characters is preceeded by "it's expected the roster will be rounded up with...", which indicates that it is speculation on their part and not confirmation. None of those names would be a huge surprise to fans and would be welcomed to the roster.
In other Mortal Kombat 9 news, the game will be at PAX (Penny Arcade Expo). According to Shoryuken, a playable demo for the public will be available for the first time at PAX on September 3, 2010. More news about the game is expected.
