DirectX 11 revolution at the door!

Hi I am interested, what YOU think that will DirectX 11 revolutionary bring in gaming field and what is YOUR opinion about DX11 Graphic cards ATI 5000 and NVidia 300 series.
Also do you think that price will be competitive?
Should we all wait a year or so or go for it immediately?
I believe there are much more people that are interested in this question.
Thank you all!

I'm a wait and see kind of guy. DIRT2 (first DX11 game) is coming out soon. Let's see what happens!
