Eventually they will, but on Google it will take a while, probably about 6 to 9 months. For the past year and a half or so, Yahoo and MSN have been much faster than Google on this, but since Yahoo's update of about a month ago, I don't know whether they've introduced a delay as well.

I believe that the delay in recovery of rankings on Google is basically collateral damage in how Google is fighting network and link spam. It's too big a subject to handle in one post right now, but the aggregate effect is that most links take a while to be credited to a site, and redirects are suspect, and it takes time to come back from a redirect to a new domain.

You may be able to speed up the recovery of your rankings by getting those sites that link to your old domains to change their links in a timely fashion after you do your redirects.
