I wonder whether NV will feature match MLAA via drivers. Driver-level improvements/"hacks" are usually their thing (ie. SSAO, SSAA in DX10/11) so it seems not entirely unlikely. I certainly hope they do so.
The problem would be if reviews are done using a configuration that not all customers will get.Oh yeah, sounds like a horrible problem..getting more shaders than you paid for..everyone, beware!!!!
