No. It will not make a comeback, and it will never make one.
Right now, most of the new projects are choosing to launch an airdrop to start the project rather than launching an ICO. Ever since the end of its hype in 2018, ICO's didn't happen anymore hence, there are new ways for these new projects to launch.

The trend has been shifted already. From ICO, to IEO, to now airdrops. We've seen many airdrops this year alone, and I expect more in the future. ICO's are long gone already, and don't expect them to come back.
