"Akame Ga Kill" chapter 67 is already available online through Manga Stream. The chapter focuses on the aftermath of the battle between Kurome and Akame. Before any spoilers on the upcoming chapters, here's a brief recap of the recent events.
Night Raid is having a night off after Kurome's battle with Akame. While enjoying their meal, Leone revealed her past misdeeds including spending Najenda's funds and drinking his booze. Najenda brushed off her misdeeds as they are deemed too small to care for. Akame was also calm during the celebration as she was thinking about the group's comrades in the past. She vowed revenge on any means necessary. The group plans to go far from the empire as soon as the war is over with Wave and Kurome.
On the other hand, Kurome and Wave settle on a hunter's cabin far from empire. However, Wave senses some eyes looking at them from afar.
At the empire, the plot against the prime minister was foiled by the minister himself. Because of their plot, the prime minister instructed Suzuka to execute the traitors. The next day, the ice soldiers were presented to the Emperor. The rebels were able to spy on the army but were caught by Suzuka. Instead of executing the rebels, she lets them run away so it could be used as a warning to the rebels. The emperor was urged by the Prime Minister to use the "Ultimate Taegu" in anticipation of war.
Shencomics posted the raw version of the upcoming manga. The war has ultimately commenced and even though Esdeath already has the ice-soldiers, they were surprised by a separate Taegu that can control animals. According to pmff96 user on Reddit, "if there is a guy who can control danger beasts, theoretically they could have already took down Esdeath. She can't get rid of all the beasts while fighting some other tough dudes..." The upcoming chapter also shows the Emperor setting up the Ultimate Taegu which could end the war against the rebels.
