Still under 200GB/month, so I guess I'm safe. :)

Next year, Comcast plans to charge home internet customers in northeastern US states for going over 1.2TB of data in a month — a cap that's already in effect for customers on non-unlimited plans in other parts of the country.
In January and February, Comcast will give its Xfinity customers not on an unlimited plan a "credit" for any data usage charges over 1.2TB during those months to ease them into the new limits. Then, starting in March, non-unlimited customers who exceed 1.2TB in a month will be charged $10 per 50GB of data, for a maximum of $100.
Customers who go over the limit will get one "courtesy" credit per 12 months, so if you go over 1.2TB in March, you get a grace period for April. If you go over again in May, you'll pay $10 for each block of 50GB up to the $100 max. Customers will be notified as they approach the 1.2TB threshold.
The affected states include Connecticut, Delaware, Massachusetts, Maryland, Maine, New Hampshire, New Jersey, New York, Pennsylvania, Virginia, Vermont, West Virginia, and the District of Columbia, as well as parts of North Carolina and Ohio.
