Since entire market is moving on move of BTC, so for ETH to get to $2000, BTC must be above $30k or so. And for that to happen, entire market cap of crypto space need to be in trillions of dollars. It's a really tough task giving the current condition of the market. I would say we won't see $2k price of ETH till end of 2020, maybe by end of 2021 ETH will make a high of $2k but not before that.
