[...] so I expect Wasabi 2.0 to come out in between 3 and 14 months
Well, that's exactly what the ETA says.
How exactly are they thinking that CoinJoin will facilitate faster mass Bitcoin adoption, with some magic tricks maybe.

Who said that?
You should try to read more carefully. No one ever said that ConJoin will lead to faster mass adoption or something along the lines.
OP said:
Wasabi announced Wallet 2.0. According to the developers, Wallet 2.0 will help Bitcoin scale faster, will also help prepare Bitcoin for mass adoption and improve privacy.
From their blog:
Therefore, our goal cannot be anything else but to make Bitcoin ready for mass adoption. To achieve this, we must start with its weakest link: privacy.
Both statements are completely true and
do not mean that CoinJoin facilitates faster mass adoption..
