Definitely. The HD 5970 is currently the fastest card in the world, and it can do Crysis with 8xAA at 1920x1200 and very high settings at 45 FPS (http://www.tomshardware.com/reviews/radeon-hd-5970,2474-8.html ). Since I don't expect the next generation of consoles from Sony and Microsoft for another 2 years, I fully expect that whatever drives their graphics will surpass or, at minimum, match the HD 5970.
EDIT: Obviously I'm talking about stock Crysis, which looks pretty damn good. Some of the screenshots you've posted look like they have custom assets/textures that go beyond stock Crysis, and with insane image quality. I'd like to know what kind of framerate people had when they were taking some of these screenshots.
