I was offput by the difficulty blurb also. Its not that I'll have problems on "Veteran" so much as that was always the difficulty I played on after the Insanity runthrough. So I won't be able to bump it up a notch, and Insanity will also be that much more difficult.
It also reminds me of the awful Dragon Age, where normal difficulty was just a hair under Insanity to start with. Unless, apparently, you were playing a mage.
