There haven't really been any serious rumblings about it in quite some time, and as I'm sure you know, it's been gone for awhile now. With MBs, MBPs, and iMacs all having them built in and the older iSight-less Macs being put out to pasture as folks upgrade, the mini and the Mac Pro are quickly becoming the only holdouts.
This could certainly be solved with an iSight-equipped Apple display, which has been the topic of several rumors over the past couple of years.
I would certainly hope to see either one or the other in the near future, but there's been no credible rumors in a long time...just a lot of hope and reasonable speculation about them.
