Reagarding Schnoor signatures, here a quote by Gregory Maxwell.
We consider it a priority, but it's only with the advent of segwit that it becomes sufficiently easy to deploy these improvements that I can be pretty confident of getting them in (and rather than having them end up as a marketing point in some altcoin.). Segwit isn't in the network yet, and there is still a sizable "online" force of people attacking it, the folks working on it (and on general fungibility) improvements-- which makes it harder to give concrete schedules.
I'd like to say that I expect to get aggregateable schnorr into Bitcoin in the next year; but that depends on a multitude of factors that are hard to predict and that I can't control.
