I know I don't only speak for myself in saying that this has been eagerly awaited for some time. For the timing, I'd support segwit being usable on the network as soon as is technically and safely possible. We at JoinMarket are very interested in eventually using schnorr which would allow signature aggregation and so reduce the cost of coinjoins.
