I can't believe so many people replied to sales' stupid post. Everyone knows why cod gets the bashing that it does when it comes to it's visuals. Naughty Dog games always show significant improvement in this department with every release. As someone said earlier, Valve has been using the same engine for ages and it's fine because it's constantly seeing significant improvement.
All they're saying here is that they're not starting from scratch like last gen, this time around. If they need better physics, they'll make the appropriate improvements. If it's not keeping the framerate they need at the visual fidelity they want, they'll work on that as needed. It's not as if their tools will remain the same for the next 6 years, people. Also, as someone else mentioned, they just like all other SCE first party, have access to a lot of resources from other devs.
