If you haven't received a notification about the update, you can manually check it out by going to Settings > About tablet > Software updates, and then hit the button to see if software version 184.108.40.206 is ready to be loaded on the tablet. Some owners of the ASUS Transformer Pad Infinity say that they haven't received the update yet and that is quite normal. No one is out to get you and ASUS doesn't hate you. These things go out in rolling waves, so try to be patient. You won't be waiting for, gulp, infinity.
