Eth2 launch has been delayed though, they say it will this January 2020, but so far we haven't seen Eth2 yet because obviously, it was postponed again.
For discussion on Eth 2.0 delays, there was already a thread created for that -
Ethereum 2.0 delays thread
I don't know what's to disagree on the list. The only argument I think is whether eth2.0 will fully launch this 2020. If it won't, then at least phase 0 will still launch which will eventually lead to that.
Reading different post in this forum, I learned that some people even think ethereum needs permission from the SEC before it can launch (which isn't true of course). Maybe that's something to be added on the list.
