Yes, technically Hedera can be very promising, in governance they took many traits from EOS, this 39 "REPUTABLE" Company Council is a bit scary, till we know, who they are, what they want, etc.
So yes, I don't think Hedera Hashgraph will make EOS pointless, which is open source, that means freedom, and more decentralized.
But I must admit, the Hedera project is very interesting and worth of attention. But for me EOS remains the most promising project. The future is exciting!
