I think they did all the stadium imagery last year. If that's the case I don't think the east stadium expansion will be included, although I would love to be surprised.
Well, I see that Memorial Stadium's capacity is set to 92k. Still not sure if the actual east-side expansion is on the game, but the capacity is there.
There's a picture in the "what's new area" of Nebraska running the option. It shows a single deck on east stadium, so I'm going to guess it's probably not in there. I remember when they finished north stadium it was another year before they had it in the game, and I think they didn't have screens on the corners for another year after that.
