The person who previously leaked that Devil’s Third would be a Wii U exclusive also said at the time that there were three other exclusive titles heading to Wii U. The unannounced games should be announced this year through Nintendo Direct presentations. Whether this is true or not remains to be seen as there were a few people who guessed Devil’s Third would be on Wii U.
“The guy that teased/leaked Devil’s Third being a WiiU exclusive said in a gameblog E3 reaction video that he knew back then that there were 3 similar exclusives (not necessarily violent, but originally multiplat/not exclusive) that were going to be announced this year.”
