Regardless of what you think. They 'promised' to release it for Ps3 ever since 1.0. They can't scrap... or else someone will sue. And you bet your ass someone will definately sue if they do scrap the Ps3.

Also they want to reach the more domestic audience. Even though the PC is considered future proof, many people don't have the time, knowledge and/or money to upgrade anyways. And yes, you can say "well they shouldn't play MMOs then" but (SE) doesn't share that opinion either...
