If they did get Arcade Endings, I doubt they'd be CG. That is usually done by a studio outsourced and costs a good deal of money, considering what its for. Itagaki was a high roller.
My favourite Hitomi ending, and one of my favourite endings overall. I wish DOA4's endings were more like this instead of the nonsense we got. I also have my fingers crossed that DOA5U will get arcade endings since the story mode is likely going to be mostly the same.
