Capcom have announced the roadmap for Monster Hunter World: Iceborn, in a nice dev diary, which you should watch and can below.

Monster Hunter World: Iceborne will get its Title Update 4 this July, with Alatreon the Blazing Black Dragon. Special events will be held from July 22 to August 6, the Sizzling Spice Fest (Seliana) and the Summer Twilight Fest (Astera).

In August, a new update will be adding the Frostfang Barioth event quest (Tempered). Frostfang weapons, armor, and Palico Gear will be obtainable. The Frostfang Barioth event will last from August 7 to 19.

The final planned update, at this time, will bring back some classic monster from games past, just no idea when that will happen. That is planned for some time in the Spring, but there is no word on when.
