I've just discovered the Wahoo RFLKT+ and the Cateye Pandrone Smart+.

The Cateye Smart+ especially sounds very interesting as it gives you the best of Cycle computer AND smart phone sync'd. The only issue I see is that it doesn't come with the sensors and so I'd have to purchase a cadence and HR sensor separately. It does however seem like it gives me the best options for futureproofing it and adding new features.

Are there any other similar options from other brands? I dont even know what I'd search for to find them.
