Ico sequel to be revealed?

Sony of Japan has posted a teaser of a website, with pretty fluttering things and not much else. Apparently, some minor sleuthing has revealed the words "Nico" and "Gengi" in the potpourri. If you follow the logic that Nico is the name of the main character in the sequel to the game Ico, then you may see where we're going with this. Spong does its best to decipher the tea leaves and reveal nirvana. Barring that, it would be nice if Sony would just tell us what the hell they're up to.
