This is dumb. The beatles catalog will become available after McCartney's Divorce to heather mills is final. Why would he go and generate all that income and then give her the rights to half of it?
Plain and simple this is a matter of keeping Heather Mills away from this money. They will deny and deny and say it will never happen until she signs the paper saying the deal is done and will not pursue him for additional money.
You want the Beatles on iTunes? Murder Heather Mills. The release will follow.
The McCartney Mills divorce decision by the Judge will be decided in about two weeks so yeah, an announcement could come soon after that.
