I don't recall where I first read about this, but it was at least a month ago, maybe 2. But I recall that the circle road around the ticket office at Cameron will be closed off, and a new central ticketing / main concourse area will be constructed that will join the two stadiums. I believe that is where the new store will be located, so that it will be convenient for both stadiums.
There are comparison plans now for WW regarding the stadium, as well as the press box / suites / etc... replacing the current press box. I actually have a pdf of that, but don't remember where I got it (maybe from a previous DBR topic?).
FWIW, I do have to say that they finally have made some positive traffic changes for FB games, but a new parking deck is sorely needed.
