I agree with Drakino. I wouldn't expect Tiger to be released any time soon. 2005 would be about right based on when they announced Panther at WWDC, and then released it commercially. In fact, based on circulating rumors, Tiger is going to be so significantly different that I wouldn't be surprised if the release were delayed beyond that. Based on how delayed Longhorn's release date is goign to be, I don't think Apple is in any huge hurry.
