Well, there was a definite pattern of poor border quality of many FX lenses showing up on FX though the quality was fine all the way out on DX (in the Canon scope that I'm more familiar with, 50/1.2 L or 17-40/4 L come to mind). But it's not so certain anymore. Does it depend on lens design (e.g. some lenses having more inherent resolution reserves than the others?) And would the 28/1.8 G behave similarly to the behaviour found in the current DX review, say, on Nikon D800? (36 MP FX is probably almost the same pixel density as 16 MP DX, since the D800 crop mode results in 15 MP pictures)
