Garmin messenger on Forerunners?

I saw a news item stating that selected Forerunner devices (including the 965) would have access to the Garmin Messenger system (?).  If this is true, that would be an awesome add on to the watch.  I can't count the number of times when I am on a run or bike ride and I see a notification on the watch from my wife texting me me to check if I am ok and I wish I could reply on the go with a simple 'yes' or thumbs up.  Instead, I have to stop, find my phone, look for the text and send a thumbs up reply -- totally disrupting my rhythm...

Hope this messenger thing is true.
