You are correct. Quicksilver is intended come out with the Mochi Miles update.

Not sure why people think they're coming with The Wilds, but it shouldn't be from the Quicksilver Slime page because it clearly says: "Quicksilver Slimes are a kind of slime that will be added in the 1.2.0 update, along with with the Nimble Valley as a part of Mochi's Megabucks Update."
