Apple has only announced a suspected time to complete it, "about a year." And I would expect it to extend beyond that, but then again, I think a preview during MacWorld '09 is likely, with a final preview during WWDC '09, and a release about 2 weeks to a month after that. So ideally, the release should be around early-mid July '09, but it could easily be delayed until September-October '09. I would not hesitate on buying a Mac now, as it could be up to 12-18 months before we see the release. And I would not expect the price to exceed $129, and I wouldn't be surprised if it were less.
