The Last Guardian Was The "BBC Secret Game".

That game, eventually caused so much hype it was entitled the "BBC Secret Game". The journalist behind the hype has now confirmed that game he saw was Team Ico's The Last Guardian and that he think it's now "impossible" for the game to meet expectation.
“I’ve carried this secret for so long that it is an incredible relief to finally be able to talk about it openly,” he said.

“Obviously, the length of time that has passed between my first glimpse of the game and its unveiling at E3 means that it is impossible for the Last Guardian to live up to the hype built around this so-called ’secret BBC game’.

“As a passionate gamer I’m really excited to see what the final playable game will be like. Ico and Shadow of the Colossus are such great titles, and the studio behind them so talented, that while there is a lot to live up to there is plenty of reason for optimism.”</blockquote>

We don't know about you, but we still believe The Last Guardian can meet expectation. That trailer was pretty bloody amazing.
