Actually there is (was) a thread on this already.
Sunken Giant ... Sadly this came
up with the other Giants cases and was written of with the rest as part of the Sony marketing scheme.
Personally I don't think it has anything to do with Sony or their game. Compare the other two
videos vs. this site. The quality is not
comparable. And the Sulu Sea giant doesn't compare to any giants in the game.
I do believe that the guy says that he is who he is, but if he's telling the truth remains open for discussion. He did not reply to any of the emails
sent to him. And no-one from any archeology department seems interested either.
Who knows, maybe sharks did eat him. Not funny, I know, but
he started it.
Yossarian, just look at a couple of threads on the first page of the Cryptozoology forum. Any thread that has "Sony" or "Giant" in the title is
most probably about Sony's viral marketing scheme for their game Shadow of the Colossus.
