Hey Miriam,
Whatever happens, I would LOVE Google to roll out a more comprehensive way of exporting Google My Business data - the API is still massively limited and the manual process of exporting data for clicks, calls, website visits etc. is an absolute killer!
Referring to your prediction number 3 on voice search, I'm thinking there's going to be way more of a focus on geolocation and we're going to see another huge rise in 'near me' searches.
All the best,
Sean
