I don't have D3 installed right now so I thought I'd ask here.

A few years ago, there was an anniversary event where you could play the D1 campaign inside D3.
--> Is this event reoccurring?
--> Is this also available on consoles?

yes
dunno

Yes, the "Darkening of Tristram" event occurs every January and lasts roughly 4 weeks. It is available on console (I play XB1 D3).

ahh i liked that event was fun

event sucked
