No, this is not valid anymore! With the new plan, there will be between 90 - 100 million of the ethers. POS change will come much sooner than planed, in about 15 months, the latest, Ethereum will change to POS.

These 90 million are due to be mined in the next 15 months. Then, and this is not decided yet, will either be a hard cap right away at 90 million or there will be introduced 2% of yearly inflation. I repeat, this is not decided. I have found this info on Ether forum.
If you ask me, this is a huge change of plan for Ethereum, on that will influence the price and everything else about this platform. The only strange thing is that a lot of people don't know about this change.
