I live 2.5 miles from the Ralph and probably drive by twice a week at a minimum. Understanding that I know bupkis about large construction projects, it doesn't look like it's a little over one week away from primetime. The store appeared to be half finished and there seemed to be a decent amount of work left to be done around the gates. Overall as of 8PM EDT today, it looked a long way from being done.
Again, not being a construction guy, it's possible I'm overreacting, but the place didn't give me the vibe of a venue that was about to host 40,000 people in 10 days.
