They're speaking about better controls and faster combat speed from what I understand, and also about making the environment play a bigger part in combat. They've also improved the impact feedback (recoil animation, monster sounds when being hit).
Finally they're saying they've improved the accuracy of targeting when hitting the Tab key, so I guess it's still a tab-targeting system for now.
