We recently announced that we’ll begin to encourage Messenger users to start using Skype. As a result, the Messenger
developer program will end. Existing implementations that use Extensible Messaging and Presence Protocol (XMPP) will continue to work until October 2013. Existing implementations that use MSP will continue to work until March 2014.

I've never heard of MSP before? Is this referring to MSNP? The original protocol for Messenger? The protocol documented by sites like Hypothetic MSN guide?
It's a shame for me that MSN is being shutting down because I've been working on a client for Messenger using the new async/await stuff in .net 4.5.
If I knew the messenger service would still be available for another year that would certainly make me happy because I'd like to finish what I started without the pressure of a 2 month deadline.
Somebody in the know, please elaborate.
Thanks
