There are so many hype around Ethereum 2.0 anmd thet eam can not afford to mess up, if they failed to deliver any significant improvements compared to what we already have in the space then I can see Ethereum losing its grip on the market, now there are some good projects all they need to do is to incentives developers to build on their platform
I don't think they're going to lose a lot if they won't live up to users expectations.
However, if they won't upset anyone or even impress most of crypto community - they'll be rewarded hugely.
Anyway, we all can feel the pressure on ethereum's shoulders, but chances are Vitalik will only release eth2.0 when its good and ready
