Absolute bollocks.
The Uncharted series' huge success is mainly due to mass bundling.
The games lifetime sales would've been: UC1 ~4m, UC2 ~5.5m and UC3 ~5m without all the mass bundling.
God of War is more comparable to Zelda, at least God of War III could sell well over 6 million without mass bundling. Hell, even The Last of Us blew all the Uncharted games sales away with a June release and no mass bundling until black friday/holidays.
