I seriously don't know what people were expecting. Team Ico isn't known for the their technical capabilities.
I also like how the game didn't depart at all from its original vision (as far as we can see) and yet people are still complaining about it being the same.
It's funny that in the rumor thread people were worried that the concept now would be nothing like what was shown many years ago. Now people complain that the concept looks too much like the original concept...
