max. supply of ether is now 105,061,446.3125 , but according this article , is there going to be a max. supply 'forever' ? 
This is starting to get serious, the supply is now close to what Vitalik proposed as "maximum" months back. Hodlers will lose confidence in ETH, if the maximum supply is now decided and coded.
Ethereum dosn't have a maximum cap, and since will transition to PoS it's a certain. However if the PoS reward will be fixed, Ethereum will be deflationary since the supply will go up but the reward will stay the same
