I think people are severely underestimating Porco. He only got taken down because he tried to strike down the blimp, which caused Mikasa to cut off his legs and then being used by Eren as a nutcracker. He was absolutely handling Eren fine 1 on 1. This time, he is likely better prepared to face Eren and even Mikasa if she joins the fray. Also, this may be the first time we have a fully focused Reiner fighting. Even with the Warhammer titan powers, without the support of the Scouts, Porco and Reiner should be able to take him on. I expect them to have the upper hand now and make Eren realize he is not not so invincible after all without the help of the people who he had arrested and alienated. I can see the arrival of Zeke shifting the tides, with him possibly taking down the Blimps and unleashing the scream.
I find interesting that Pieck is well aware of all issues the Eldians face, and she pointed out that she doesn't trust Marley, but she does oppose Paradis and still fights for Marley. I think her phrase "I trust my comrades" means that, just like Paradis is currently divided into factions, so is Marley. Following Eren's attack, much of the Marleryian Eldian-hating leadership died, and Margath has pretty much taken over the military. She trusts him and the soldiers who have fought alongside her and, from what we have seen, Margath doesn't seem to hold Eldians in contempt. I like to think that she has a evolved form of Gabi's mindset. She is very well aware that she is used by Marley, but gives her best to gain the trust and the respect of the Marleryans who fight alongside her, like Margath and the Panzer Squad, and counts on their support to help protect Eldians when they lose the relevancy to warfare technology.
