Eth 2.0 mainnet is expected to go live by November this year and according to my info mainnet will also bring the long awaited change to pos algorithm and also sharding that is expected to make eth network efficient and improve its capacity a lot.
I am all in for eth 2.0 release this year and feeling excited and bullish for it.
It's highly possible that ETH 2.0 will launch this year as promised .may be in November and the DEFi hype is helping it's part too. But the full fledge working one will take 1-2 years more
November is their target date, so what like two months from now? So still a lot of time for them to really 'perfect' this ETH 2.0 and I'm sure if this is going to be release as plan or even a slight delay this year? the altcoin market will really took off, with all the Defi and UNI or Sushi swap going on. They know, that's why they're definitely working 24x7 to stay on track and hype the price of ETH to $500 or even more.
