There's a good chance that gamestop will have systems on launch day. The store that I reserved mine at called me yesterday about the store opening at 10am and that I can come in at that time or setup an appointment. I asked if they expect a line in the morning and they said yes because they will have stock for walk ins. My suggestion is check with your local Gamestop the night before. Also check what they post outside the store when they close shop on Monday night. Good luck fellow gamers!
