One can reasonably expect the Sterling to mean-revert over the course of the next 18-24m as Brexit fears prove to be a furphy. I expect the distribution to remain the same post-Brexit.
Gold is trading at the upper extreme of its regression channel since it broke down in April 2013. Deduce what you will based on your own trading strategy, some may view this as a potential break-out, others might play the mean-reversion. I'm agnostic for $DXY related reasons, so I will watch closely.
