Understood, but I would hate to accidentally set false expectations, as plans change all the time (we like to stay nimble).
Our rule is to only talk about next version's capabilities when we're close to feature complete of the corresponding release (normally 3-6 months before GA). Not only because we don't like to sell future, but because we hate to [accidentally] lie to our customers about features and dates - and thus lose trust. Trust is most important - we'd rather lose you to the competition but keep your trust, than the other way around. Because with trust in place, we can always get you back - especially in this new no-commitment world of subscription-based licensing.
That said, I can certainly confirm that both SharePoint and OneDrive support are close to the top of our priorities list, which in fact was just agreed upon earlier today with all stakeholders. But, a lot will depend on v1 feedback - starting from public beta later this month.
