Will there be an ICO for ETH 2.0?

Sorry if this is a completely retarded question, but im quite new at crypto and im still figuring out how the main coins work.

I was wondering what exactly will happen to current eth once eth 2.0 launches and if there will be an ICO for ETH 2.0?

Will ety 2.0 be considered and traded as a different coin?

For example, if there is an ico for eth2.0, once it launches (maybe even before), current eth value would probably drop considerably and eventually have no value, cus eth 2.0 would take over??

If anyone could clear things up for me id appreciate it, thanks.
