When will EIP-1559 be launched on the main net?

I've read about the success of the test net and how over 85,000 ethers were burned. There are 2 more scheduled test nets, that is Goerli and Rinkbey and they are scheduled at the end of this month and the beginning of next month. Each of them are supposed to last only 24 hours.

At the same time, I've looked at the inflation rate of ether and it is currently at 4.4%. The ether supply has actually increased to close to 116.5 million.
