The new upgrading system with Armor Spheres will also be added on the 16th, and Uragaan on the 9th (next week).

It also mentions that Switch Axe F won't have the same unlock conditions as Tonfa, not being a G Rank unlockable weapon, so anyone can use it.

Oh and the Dual Savage Deviljho quests are back for this week.
