Just to point out, those shots are all old, well since Sept-November and yes this game has its great visuals ruined with jaggies.
This is my biggest gripe with the game, then we have to remember even FM2 suffered quite badly with jaggies. Its seems its 60 fps with jaggies this generation or 30 fps with AA.
My own personal belief is that with this game its a problem more on horizontal lines and this is caused with the scaling of the rumoured 960x1080 native res scaled to 1920x1080. Hence a 2x increase in the horizontal plane. What you have to remember is that this is still quite a bit below 1280 horizontal (for 720p games). I can however confirm that on tests i done with both a 720p and a 1080p projector that with a 1080p display the jaggies are ever so slightly decreased, but mainly on the vertical plane were you get the full 1080 res against a 720p vertical scaled res with a 720 display. The benifit is not worth rushing out and getting a 1080p display, games however that are 1080p native look incredible on a 1080 display that i can say for sure and particulary on a large screen or projector.
Im afraid your gonna have to live with the jaggies guys
The game does imploy some AA to a certain degree as owners of GT HD and GTP5 have noticed, for instance the electric cables at the top of the mountain on tracks like Eiger Nordwand
