Here's links to the site plans submitted to the City for the east gate renovations and west tower (press box) and concourse modifications. (Can't find the stadium modification/track removal plans right now. The City may have removed them. There's a previous thread on this subject.)

I was originally against the track removal, as I didn't see why we would remove the chances of hosting a major meet, plus spending money on building something we already had. But a story about the track team changed my mind. They have very limited access to facilities during football season, since the football team had priority. With schedules so tight, multi-function facilities create a problem. It's one reason Duke built the new basketball practice facility, so that Cameron could be used primarily for games/matches.
Same with the sports medicine facility. The sports facilities team doesn't get access to the facility until late Friday evening, after the medical teams are finished. It also limits the medical side from providing services during fall weekends.
What worked in the '20s and '80s (when the stadium and track were built, and when the sports medicine facility was opened) isn't necessarily the case now. Same with other facilities across campus, most noteworthy the library and union right now. Of course, there's the thought that the new club seating will provide additional revenue, hopefully paying for itself. But most of the changes are to bring WW up to modern standards (the bathrooms, as I'm sure you know, date back to the original stadium. The new facilities are very much appreciated!)
Regarding the stadium changes, there's a story on GoDuke.com, written by Al Featherston, on the facility upgrade plans

the first changes to be finished will be removing the track, lowering the field about five feet, and adding about seven rows of seats on the sidelines, and ten in the end zone. The field will be centered in the bowl (moving it about 2.5 yards towards the closed end.) It seems from publicity/articles (but a detail not shown in the site plans) that the new stadium walls will have a "Duke Stone" veneer similar to the facade on the new bathroom facilities. This should be completed in time for the 2015 season.
The east gate will be moved a little towards the open end of the stadium, and the concourse will be leveled and "enhanced" (my word) by putting in a difference surface and removing the asphalt. New concession stands will be included. The president's box will be removed with new handicapped accessible seating at the top of most sections added. This also should be completed for the 2015 season.
The west tower (press box) will also include leveling the concourse, with the entrance being modified to include a bridge connecting it to the second level of the press box, and ramps going down to the entrance to the main concourse. (From a grade standpoint, this makes sense, the entrance currently is well above the concourse at the top of the seating area.)
There's also plans for a multi-level parking deck to be built on the current 751 lot starting in early 2015. This will provide parking for sporting events, but primarily serve the business and law schools.
