We should note that last year's Winter event ended in early January, and we'd expect this year's event to run into the new year as well.
Several maps will also get a Winter facelift, namely King's Row, Hanamura and Black Forest.
According to Overwatch's director Jeff Kaplan, he confirmed that Legendary skins will be available, such as a Legendary Hanzo skin that was teased in the comics, along with Legendary skins for Junkrat and Roadhog.
It appears that Blizzard has listened and that this skin will be coming to the Winter Wonderland event that drops next week. Also making a comeback in this year's edition of the Winter Wonderland Event is the "Mei's Snowball Offensive". These limited time decorated maps are always just lovely and Kaplan described this as "one of the most gorgeous jobs [Blizzard's] environmental artists have ever done." so we are in for something special this year.
Along with new holiday skins, and past event skins will return alongside Mei's Snowball Offensive alongside the new Brawl, Mei's Yeti Hunt. What's new here is it's expanding to the Black Forest map too, and a change in scenery is always a nice addition to have. Yeti Hunt will see a team of five Mei players - with slightly different abilities - have to hunt down one player as the Yeti aka Winston on a modified Nepal Village map. Boss Winston who is also controlled by a player. If Winston kills enough Meis, he wins.
If one thing makes Overwatch so popular and makes players go back to it even after long periods of inactivity, is the game's events. The Winston must collect meat power-ups to enter Primal Rage mode, at which point like an Overwatch version of Pac Man he can turn the tables on the Meis and hunt them down.
"I know a lot of you are thinking it sounds kind of ridiculous and kind of silly, and I'm here to tell you it absolutely is", Kaplan said.
