There are projects like Cardano and Zilliqa, but then there are some like Orbs that are using blockchain virtualization claiming it can work in tandem with Ethereum.
I assume Ethereum will implement some of its solutions before that 2020 date, but they will probably need to rely on more partnerships to do it.
