Valve has announced that Dota 2's holiday-themed Frostivus event is on its way, though exact details are still somewhat sparse. The announcement, made via the official Dota 2 website, says only that "Frostivus is coming." The page hints at content to come, including what appear to be new crafting items and some sort of gift exchange in addition to the obligatory event-themed chests. The frosty, snow-covered map of Frostivus 2012 is also likely to return.
Fans of Dota 2 will remember that last year's Frostivus event was canceled due to an influx of gift-snatching Greevils. We'll just have to wait and see if the same tragedy befalls this year's festivities.
