When ThinkSecret announced last week that OS X 10.4 ("Tiger") will ship in April, there was a fair amount of skepticism. A number of people suggested that there were too many bugs in the current developer seeds, and Tiger wasn’t ready to ship yet. Since then a few other reports have surfaced, including one from eWeek that seems to confirm at least the timeframe, if not the exact days that ThinkSecret listed.

Today, ThinkSecret followed up with a new report, saying that Tiger development is rapidly winding down and suggesting that many parts of Tiger are already complete and ready to ship:

Multiple sources also report witnessing at least one Tiger “wrap party” at One Infinite Loop earlier this month, and several members of the Tiger development team are presently on vacation, sources say, generally a sure-fire sign that their portion of development has been completed.

Personally, I’ve been drooling over Tiger since it was first announced last year, and can’t wait to get my hands on the new release.
