10) Will the Office Add-ins functionality and features ever be equivalent to that of VBA or VSTO ?
100% parity might not be possible, due to the multi-platform nature of Office Add-ins, and the fact that certain Windows functionality is not achievable on other platforms.
A lot of progress has been made with the JavaScript APIs (especially Excel and Outlook).
A large number of solutions are now possible using the JavaScript APIs so it's a good time to get started.

11) Can we migrate our existing COM add-in to an Office Add-in ?
There is no simple migration path, you will have to create the Office Add-in from scratch.
Not all the functionality in your COM add-in will be available in the Office JS APIs.
