On reflection, my previous comment was off the mark. Knowing that Omega always predicts "two-box" is an obvious correlation between a property of agents and the quality of prediction. So, your correction basically states that the second view is the "natural" one: Omega always predicts correctly and then modifies the answer in 10% cases.

In such case, the "simulation uncertainty" argument should work the same way as in the "pure" Newcomb's problem, with the correction for the 10% noise (which does not change the answer).
