Hey there! If you're asking if there will be the annual christmas livestreams this year then I'd assume so, due to the fact they've been on conceutively for the past 4 years now. If there's any change, I'm sure someone as The Yogscast will let us all know.
Also, to add to what Gavalar said above: The Yogscast do not own, nor visit this wiki, so this wiki is not the place to ask questions. Instead, try to contact them through their reddit and/or Twitter as linked above!
