High end != new technology!
Even if you use DX10 level hardware as min requirement, you still need baked shadows etc unless you plan to restrict your users to HD 2900XT, 3870(X2) and 800 series cards of NVIDIA.
Because 8400, 8500 and 8600 won't be able to handle all the intense additional maps + shadow maps in realtime within a real and not tech demo environment.
Just because hardware supports SM3 this does not mean that you can become lazy in scaling your dynamic and static contents towards the target machine or you won't have many costumers.
Entry, Low-end and mid end hardware won't be able to keep that arrogance on a usefull FPS level for the next few years.
