This is the Coinbase's list from Sep 2019 . So far only Orchid is listed. In my view, the ones most likely to get listed in 2020 are Polkadot, Avalanche and Near. Solana probably in 1H2021. 
The coins that have launched that are not listed yet incl Celo, Kadena, Nervos, Handshake, Solana and Polkadot. Near and Avalanche are very close. The ones most likely to get listed in 2020 are Polkadot, Avalanche and Near. These are the assets investors care about.
There is also strong interest in Solana but given its limited circulating supply ATM and a major vesting coming in Dec 2020, I think a 1H2021 listing is more realistic.
If you believe Filecon's launch timing (Aug 2020), they may also be a listing candidate in 2020 or 1H2021. Given their big warchest and major VC backers, Filecoin will get some priority consideration.
Most of the others on this list have uncertain launch timing (eg. Chia, Dfinity), have fallen off the radar (eg. Oasis) or are dead (Gram).
I'll be reviewing the June 2020 and July 2020 lists next so stay tuned.
