Bright Side of News claims AMD will introduce the Radeon HD 6000 series at a press event in Los Angeles on October 12th, 2010, but it's unknown whether this will be a soft or a hard launch. Interestingly, the mainstream cards are expected to arrive first:
Unlike the regular launch sequence, AMD plans to introduce the mainstream series first, meaning headaches for nVidia's Sales team and if you're a consumer like us - welcome Holiday Season 2010 with the two graphics giants slaughtering each other.
