Do you guys really think they would add Donovan as an extra character? He is like the bad guy of the series, if he is going to be playable or even being a boss it should be in DOA6 or DOA7, etc...
I just read the full article. Apparently, PS4/XONE users will may get new stages/characters in the future. That doesn't affect me, since I'm in 360, but they are very good news :)
Probably TN didn't put so much work in his face because they didn't have planned to reveal it. Just look how much time it takes to have a costume with his face exposed, even in the swimsuit for the guys he still have the mask.
