According to Microsoft-watch.com and reliable sources, MSN are planning to release Messenger 7 into beta testing on BetaPlace as early as next Tuesday. We exclusively revealed the new client yesterday amongst a lot of hype and anticipation. MSN were due to encorporate some added features into MSN Messenger 7 but it seems like these are delayed until a later "wave". For those wondering, a "wave" is a release (be it .1 or major).
MSN Spaces integration: Blogging straight from MSN Messenger Window
Personal Information Management: Intergration with MSN Explorer to truely manage your contacts and build lots of information about them.
Since MSN Messenger 7 is now due to beta next week, the public preview will follow in November and an earlier final release is now expected.
The latest build is 207 and we'll keep you updated as always :)
