Hopefully in time the 1.6NA goes away. It's a decent engine for what it is. It an aging engine and not real high-tech. Once the 1.0L becomes proven to be reliable over hundreds of thousands of miles of driving, maybe then it will become the only engine offering. Goverment fuel economy standards are only set to continue to rise and more fuel efficient engine options will be continually needed.
Even if Ford doesn't use the 1.0L as the main engine, I look for a NA gasoline direct-injection engine as a future option for Ford. Some of Fiestas direct competitors, like the FIT, use a new direct-injection engine. An engine like that is still cheaper than something turbocharged but still brings better fuel mileage and power and torque to the vehicle.
