I think anyone would have trouble making a lens in this class lightweight. Well, maybe DO would help. If it can be kept in the 3kg ball park that is ok with me. (roughly, canon 200/2 2.5kg, sigma 120-300 os 3kg)
What would sell me this lens is if it has well controlled spot sizes off axis and good (low) LoCA. The 120-300 does well in those respects, at least over APS-C coverage.
