Tron cannot collide with ethereum, as these are coins with different directions in their development. For various types of cryptocurrencies, there are still many areas of growth and they are capable of both competing with each other and supporting each other. Tron 4.0 is not necessarily the answer to Ethereum 2.0 enhancement development. Each coin develops according to its plan, and each stage of such development requires a lot of effort and time for preparation. Therefore, most likely, this is just a coincidence.
