Current implementation needs different AA Bits (or with your words hacks) to get blur free SSAA in many games, but it doesn't mean with a proper implementation blur free SGSSAA will be impossible sometime like AMDs SGSSAA. And by the way can you answer JimBobbs question? Which games exactly do you refer? AMD profiles are closed, if you change the exe from another game you might be able to apply this game profile in order to get AA working. This isn't different to changing AA Bits basically, it's just the only way on AMD cards currently since their profiles aren't accessible to everyone. I don't see how it proves they are using game hacks to get a free of blur SGSSAA. I don't think they apply hacks manually to hundreds of games to get a blur free SSAA. I think their implementation basically works in a different way and that's our goal to have on Nvidia cards as well. They could release it with their SGSSAA tool inofficially. That has nothing to do with it. DX10+ games doesn't allow driver forced AA mode not matter if MSAA or SSAA.
