Almost all of those were already announced titles that were simply had demos shown. The examples of "unveiled" games in the article you linked to are Uncharted and Heavenly Sword, both of which are already on the list, and GTA IV, which isn't even exclusive. I'd be curious to see how many of the "unveiled" games at Sony Gamer's Day were really totally new games not on the "Exclusive Arms Race" list, because I actually haven't seen any.
Edit: Hold on, I thought of Socom. There's one. If any one has more, let me know.
