After the ETH 2.0 hard fork, what will the two different currencies be known as?

In the 2016 hard fork, Ethereum split into Ethereum Classic and Ethereum. What would would the two currencies after the London Hard Fork be named? Would they just be ETH1 and ETH2.0? Because it seems that one of the currencies should be able to use the name "Ethereum" and the ticker "ETH".

Also, Coinbase has a listing "ETH2". Is this the actual Ethereum 2.0? Won't ETH2 not exist until after the hard fork? And will that be the ticker for ETH2.0?
