EW blurb on final episode

There is a little section on page 13 of the new Entertainment Weekly that talks about the last episode. It doesn't give details, but it does say that the actors that played many of the bit characters over the years have been asked to clear their schedules so that they could be in it. Some of these mentioned include the Soup Nazi, the "old bag" that Jerry mugged, and Keith Hernandez(!). How are they gonna tie everyone into it? It almost makes me believe the guy who posted the story about the episode being a parody of "The Game" , but I don't believe that because if it was on the 'net, it's probably fake.
