new Chicago and Brazil districts?

There's been a pile of new loot added into our Mafia Wars inventories, among them what appear to be 4 new consumables.

The Lexington Room Key, shown above, says it comes from Chicago. But I don't recall this dropping from or being required for any current jobs available in Chicago, including the City of Traverse secret district.

And the Tipster just says that it comes from "jobs", but it looks very Chicago.

Antivenom may come from Brazil, according to inventory.

 The Canistern also says it comes from jobs.

I guess we'll have to wait and see.
