COULD have yes. Do we know at this stage whether they will even be supporting the old +X on armor and shields? It would be fairly counter productive to the prerogative to flatten the probability math to keep those bonus's on armor and shields.
In the absence of any solid proof to the contrary (and if you know something, please give me a link) Im actually guessing that +X on armor and shields will be a real bad fit for the direction they are aiming for, an the concept of enchanted armor and shields will have to follow a different model for implementation.
Old +x style Armour is in the playtest. But take that how you will.
