Jim, you're a bit behind 
Two threads on this, the "general" 2017 CB thread with 7 pages already:

and a separate thread for the RS model:

Specifically to your question, the tank capacity will be 16.8 liter on both the new models, which is 2.2 liters up from the 2013/14 standard, and roughly the same size (i think?) as the DLX.
