Chinamaniac recently reported this story about Stars making the official announcement of their Full Tilt purchase "in the third week of May":

Now he has told me that the announcement will come "this week or next", and that he has gotten reliable information from his inside source.
While I have not personally communicated with this source, I can tell you with certainty that:
1) Chinamaniac does have a real inside source
2) That source does have a lot of information regarding behind-the-scenes matters at Pokerstars
So I think it's likely that his story is true. While it is possible we will see more delays for logistical reasons, I do believe that, as it stands today, Stars indeed plans to announce their Full Tilt purchase on or before May 25.
