I just heard Justin Sun announce that "TRON 4.0 is coming", maybe this is his answer for ETH 2.0 
As Ethereum strives to be a "world computer," TRON also aims to accomplish this feat, but focuses more on decentralized entertainment.
Justin Sun have make the TRON4.0 announcement long ago and he also set a polls where people voted for the protocol they think will win between TRON4.0 and ETH2.0 but one think I understand is that Justin is trying to win ETH supporters heart.As Ethereum strives to be a "world computer," TRON also aims to accomplish this feat, but focuses more on decentralized entertainment.
Perhaps the basis for Sun to believe that TRON overtakes ETH in the Daaps market is that TRON has more blocks and transactions, is fast growing and has many use cases, as well as a proven record of proofing. Browser.
The last time i checked every project that offer Dapps will always live in the shadow of ETH and what Justin dont understand is that it not always about TPS but trust and if it about TPS BTC wont have hold the number spot in crypto market.Therefore, theres no battle between TRON and ETH cause ETH has already won.
