[quote name='KingBroly']Pop in a game and it should prompt you. Read my previous post for shennanigans!
Try using the blades or loading up the games marketplace.[/QUOTE]
Did that, didn't work. I just cleared my cache, so I'm going to try and see if that will prompt the system update. I'll let you guys know if it does, it could be the work-around for people who didn't receive it yet.
Edit: I can now confirm this works. So if you update a game, and still have no system update prompt, clear your cache and then update a game.
