Fumito Ueda's next game (he's the ICO guy)

So, according to this 2005 article, Ueda already had a few ideas in his head. It's two years later, so it's likely that work has begun on something by now. What are your thoughts on that? Would you rather have another action oriented title like Shadow of the Colossus or something more intimate like Ico? Maybe something different altogether? TGS is only a couple months away...
