Achievements have always been a big part of the GTA experience in some form or another. Of course, I am not talking about the 360 achievements system but the stats on how many people you have killed, cars you have stolen, jumps you have made etc that has always been available in the pause menu.
I expect like all the 3D versions before it, this feature will still exist in some form on the PS3 and 360 versions. Of cours,e a little notification flashing up on screen to let you know you have achieved x or y will be cool but I don't think that it will be too sorely missed on the PS3
As for the exclusive content, this article has it all wrong. It has been stated categorically by Rockstar and Microsoft time and time again that the DLC missions etc are exclusive to Microsoft. I dare say the PS3 will get something, but my guess is it won't nearly be on the same scale.
