Sony preps 3rd version of PS3. Why won't they focus on the current one?

"You'd figure Sony would concentrate on getting their existing two models of PlayStation 3 into peoples homes before developing a third, but that isn't the case. Sony is looking to introduce a multimedia-oriented PlayStation 3 soon, designed to be a multimedia center rather than as a gaming console" -TechReport . Hey Sony, FIX THE CURRENT VERSION!!
