New yellow, green, blue and red cannons have been uploaded and are in the new Community Store owned by MaxisLee in Test Center 3, without being announced. It is still unknown whether these will be given as gifts, will be added in the buy catalogue, just a recolor of the original cannon by a tool that will be introduced in the future or just exclusive objects that can be bought at only the Community Store.
Furthermore, the ATM machine that Sarah from the development team is currently working on has been already only added in the Community Store. Surprisingly, the ATM machine is not yet done and which explains why it is unclickable. We are still waiting to see what will happen in the future as the new cannons and ATM machine seems to be just around the corner.
Some pictures taken by the admin in the Community Store in Test Center 3 showing the new cannons and ATM machines:
