When will Windows live mail (Desktop) new version be available?

Secondly will this app be available or discontinued like outlook express?

Whether social updated will be available in future or not. 

I am using this app since last 3 years and like very much. I do not like to switch outlook 2013 on Win 8.

I bought a laptop with win 8 and thinking whether to choose Win 8 mail app, WLM 2012 or Outlook 2013.

I have to configure my email, If this would be discontinued in near future than should I start to use outlook 2013.
