Luckily, lot's of commercial parties seem very interested in ROS 2.0 which gives me some good hopes for a less painful transition from ROS 1 to 2 than from Python 2 to 3... But given the federated development of many non-OSRF maintained packages, the bridge between ROS 1 and 2 is going to be used for a long time, I'm afraid. But it's possible at least to mix the versions.
