Some people are smooth lmao. On Twitch, some players leave the game title as DOA6 while playing DOA5LR so that the latest viewers stick around. Smart, since people or newer players tend to only follow the latest norm or whatever is new. So you make 5 look like its the latest raising it's popularity sorta.
For heads up, it's not the final update of that game. It's only the final "DLC". They still have to patch out Tamaki's 4H+K and like 15 other bugs from that character, but that may also be addressed on that last DLC itself so who knows.
You guys should check up on Itagaki's official FB page regarding the whole hair situation. He was going in lol, he wants DOA to completely stop continuation as he feels it's being tarnished. Even then...he's not in the company anymore so he can't really do much at this point lol
