I don't have any numbers, but lets try to reason about this anyway.
Today, if you post a comment, someone sees it, and thinks is interesting, they'll upvote it. It seems reasonable that a comment on a fresh story (eg: on the home page) is more likely to be seen, and it might be more likely that a comment will be upvoted while it is still "young".
With the new system, you will get no karma until after some 1k karma curator notices your comment. Being approved (as I understand it) grants you no karma in and off itself, while (as someone else mentioned) normally that approval would've been equal to an upvote before. So if that's the case (easy fix: make upvote=approve) new comments on average earn one less point (so I might end up at .61 average, not 1.61 -- possibly fair indication that I talk too much).
At any rate -- anyone below 1k won't be able to upvote the comment until after approval, I don't know what kind of impact that'll have -- but it certainly means new users come to a substantially different playing field than old ones.
