I know what the ice age mechanics is and why it was created. I was referring to the complete uncertainty about the transition to PoS. ETH mining won't last for long and there is no clear timeline for the transition to occur.
Let's not forget that the whole roadmap to Casper, including the ice age bomb, was devised when ETH was trading round the $7$8 dollar mark. The huge price rise and the tremendous expansion of the Ethereum Alliance might have changed the game completely.
@trimegistus I know you're a senior member but you may have missed the latest news. I'll post here for you and others. I don't mean any disrespect to Trim and I'm not even sure of the validity of the info I'm posting. Maybe we can get confirmation from a second source?
Casper is going to be delayed again. One of the ETH devs current estimate is end of 2018.

ETH rewards will be decreased to curb inflation...
