Yes, as I told you in the e-mail I'm very sorry.
Yes, they are working on something for sure. In February 2007 the team started looking for new members, just like you said. Development would have started a bit before since it wouldn't be financially viable to start looking and employing new people if you're not going to use them straight away.

No, sorry. Sony took it down shortly after Shadow's release. But luckily enough some pages were archived:

Basically a guy continued a story which Sony came up with to promote Shadow of the Colossus. He registered an e-mail address which Sony listed on one of the viral blogs and started sending e-mails to all those who were looking if all these stories about giants being found were true. Sony then adjusted their own story to accomodate his twists.
Err... no colossi is plural of colossus.
Anyways, the title is grammatically correct since the article talks about 3 colossi and not one colossus.
Yup, Team ICO is part of Sony's JAPAN Studio.
^ Well ICO was the team's first game, hence the name "Team ICO."
Tsutomu Kouno, creator of Locoroco and who works on the same floor as Team ICO reported in an interview some weeks ago that the team is surely working on 'something'.
Interview was done by Joystiq.
Much of the stuff we know about the next game:

Basically all we know is that it will be for the PS3 and probably set in the same world as the first two games.
