Ethereum easy 2k within a month or two 
It's too early to talk about $2k, I'm going to go to $1k in a few months, because not always will prices continue to rise, there will always be a correction in the middle of the trip.
Yes, it is impossible for any coin to increase it's price continuously and at one stage the price of ETH will surely cross the value of $1k but we don't know exactly and how long it is going to take for the ETH to reach that value. Now Dominance of Bitcoin is complete high which it will take some time to recover the prices.
