Masamune and Keiji being Orochi's underlings is a form of Take That to Sengoku BasaraSengoku Basara 2 introduces Naoe Kanetsugu as a pathetic Joke Character a la Dan Hibiki. Koei doesn't like one of their main trio getting reduced like that, as a result, they snap back at Capcom by making two of Basara's poster boys (Yukimura is also Koei's poster boy, so he's out of question) underlings of Orochi that you need to beat down and label 'bad guys'. Not to mention Masamune, being the more 'main' poster boy of Basara, is turned into a worshipping fanatic of Orochi, stripping all his Badass points in his KOEI incarnation (it's less than the Capcom one, but STILL).
The third game will continue the story, and expand it to the next generation DW and SW (DW 7 and SW 3)Which means, most maps get a revamp for nextgen maps, and they will include Bao Sanniang, Ma Dai, Liu Shan, Guan Suo, Cai Wenji, Jia Xu, Ding Feng, Lian Shi, Sima Shi, Sima Zhao, Wang Yuanji, Zhuge Dan, Guo Huai, Zhong Hui, Deng Ai and Xiahou Ba for the DW side; Kato Kiyomasa, Kaihime, Kuroda Kanbei, Hojo Ujiyasu, Tachibana Muneshige, Takenaka Hanbei, Mouri Motonari, Aya Gozen and Fukushima Masanori on the SW side. Plus Musashi and Kojiro returns.
The 4th game will have Kenshiro, from Ken's RageOne hell of a pipe dream, but they don't call this section wild for nothing. Also, holy shit IT WOULD BE SO AWESOME
Warriors Orochi 3 will be made playable and accessable in stores in the US.When they release the Warriors Orochi Collection, look back at other series. Jak and Daxter, Sly Cooper, God of War, Mega Man In a year or so they will release all three games and you don't have to download it to play it.
There will be a fourth game and it will come after SW 4 (AKA somewhere in or after 2014)They could just whip in a Continuity Reboot for the WO franchise. It's inevitable as the series they're picked from will continue to grow and Koei would probably give them a chance to encounter each other again. It will have Abe no Seimei and Shennong from get-go. The newest addition of the cast would be Xu Shu, Guan Xing, Guan Yinping, Zhang Bao, Yue Jin, Li Dian, Lu Su, Han Dang, Zhang Chunhua, Jia Chong, Wen Yang, Takatora Todo, Yagyu Munenori, Ii Naotora, a Bladestorm character (probably Edward the Black Prince, the main 'face' of the English forces), a Trojan character, and for the 'modern day/ Ninja Gaiden' representative... well, the most recent addition of Hayabusa's lady friends after Ayane, Rachel and Momiji: Kasumi. Maybe for PS 4?
