Haven't played the uncharted series I take it?
Haven't played Crysis on absolute max I take it?
Or Metro 2033 on absolute max?
Point is, what Uncharted is doing on the PS3 was already done like a year or two before it's release on the PC. And since then, the PC has gotten even better. The absolute best graphics on consoles these days are nothing compared to the absolute best on the PC, and they never will be until the next generation starts. And even then, it'll only be a matter of a year or so before the consoles become dated again.
As for the matter at hand, I doubt Skyrim will have any form of AO at all. Bethesda isn't really the type of developer to add in any graphical extras on their games for the PC versions. Maybe some slightly better textures here and there, but nothing like AO, Dynamic Depth of Field, Global Illumination, SSS, etc. And they're definitely not the type to add in functionality for other API's like DX10 or DX11, so that means no proper soft shadows, no tesselation, etc.
Besides, Todd already confirmed that the only extras the PC version will be getting is higher resolution textures, adjustable AA, and the ability to play at higher resolutions.
