As a huge Scala fan, I fear that Dotty will suck the oxygen away. In particular, freezing the syntax for as long as the proposed timeframe for Dotty to be delivered would kill any language.
I would urge typesa^H^Hlightbend to bring forward the introduction of vital syntactic features from dotty (e.g. existentials as HKTs, if they really think that's the best way to express type lambdas). Even if that involves making large changes to scalac that will have to be thrown away, the Scala community cannot survive with the syntax the way it is for much longer.
