They should have a limit, really they should of had the game released and been working on another title by now. I mean the game was revealed in 09, which means it should had came out that year or the next. I kind of thing the game was scraped and started over again, or is being put on the ps4 instead. There just better be a good reason for this.

ND didn't start the gen that size, the increase has been so they can release more frequent games, but they will have launched at least 4 titles since Team Ico did anything and all the titles released have been critically and commerically succesful. They are just pointless if they take this long to make games. If they came up with a good idea that could make money, Sony might give them some more resources, but they just aren't doing anything productive

Getting the Ai system work is more complex and time consuming than doing graphics and textures.  They probably had problems with the animal's AI and his behaviour with the player, what they had in mind was too ambitious and required too much work I reckon.

I honestly don't care anymore about the game. Maybe if it haves a book I will give it a read.

I think it's the AI too. The AI proposed for the game is way more advanced than any AI in any videogame. Add into the fact that team ICO was never really technical wizards and you've got problems.
