Yes, you are correct. Currently it is only for type 1.  The article mentioned they are hoping to make it functional for type 2 also. "While the device can currently only be marketed for Type 1, doctors said it could eventually be used by those with Type 2 diabetes, where the body gradually loses the ability to produce or use insulin. Many of those patients are overweight or obese and face increased risk of heart attack, stroke and kidney failure." Can you imagine the size of the obeasts of the future if they got this?  It gave me a nightmare vision of an obeast with mechanical limbs and an artificial pancreas storming through a city in shambles from rising expenditures on healthcare.
