Avatar level of detail...common, whilst in theory it could possibly be archived, not yet. To produce that much level of detail, the texture resolutions, the geometry, shaders and physics every would have to be completely custom and far more power full than any hardware released to date!!...meaning a real freaking expensive console.
But on the up side, all these gaming companies that are becoming "sell outs" or holding back and only make a cheap PC port **cough** Crytek **cough** will have a new benchmark to play with... at least until the "720" "PS4" are out of date in a year.
