I was under the impression that the first newspaper chopper read was about the planned execution of Ace, like the one grandma nyon gave to Luffy. The newest one Chopper got on the last page was the outcome of the war, and Chopper freaked out about Luffy jumping into the middle of that fray.

Its been established that Amazon Lily is the best place for Luffy to be right now, so I'm sure he's going to stay there until his training is done. In other words, the last page probably wasn't a cliffhanger.
