Last week the Bink website announced wide availabilty of the new incarnation of Microsoft's Messenger to be released on June 16th. Today WinFuture has been informed by their source, who is involved in the launch process of the software, that Windows Live Messenger 8.0 won't be ready for a 06/16 launch. One Neowin member speculated that this was to do with a bug issue that needs taking care of.
It's anybodies guess as to the reason -one thing is certain, Microsoft release dates are not officially announced for a reason. They simply have the habit of slipping beyond their own target dates.
