What are your takes on the Marines as a whole separating from the Government? Will they or not, or will it just be a faction like we all originally thought? Oda created a visible schism between Sakazuki and the 5 Elders, and both the Marines and Government have top secret factions involved in activities the other wasn't aware of. I'm not ready to say either way. The safest option is that only the good Marines will fight against the Government in the final war, but Oda could go the whole free for all route during the final arc.
Going even further, if Sakazuki wasn't aware of SWORD, then this may create further tensions within ranks. Especially if there are more members that are part of SWORD.
