In this video, they talk about the Universe Mode, between 4:55-5:40
They said they made a lot of great improvements in the Universe Mode but since there are so much information they have to reveal regarding basically all the entire game they do not want to just reveal everything at the same time, they want to reveal information gradually but they said they will reveal some of those improvements soon.
I just hope they include in those improvements some (ALL!!!) of the things I mentioned earlier, because those will take the Universe Mode to another level, making it so much better. It will sure as hell provide me with one of the greatest wrestling video games experiences ever.
