Most probably. Small team, etc. as others have noted. In looking at a title like this it's important to understand it's not aiming for huge numbers - a good analogy would be a mid range cost film aiming for a small profit and high acclaim.
That's exactly what I expect from The Last Guardian, high critical acclaim - probably some awards for the Sony award cabinet - and an okay profit to cover the support of a more artistic development team.
TBH the Team ICO guys (and gals) are the closest thing in the gaming world to how Kubrick was for me in film. High acclaim, unique work and modest sales/profit but a disproportionately high recognition in the industry. Team ICO have that - with ICO and SOTC having an awareness and critical reception way above their actual sales.
Try to be reasonable... its easier than you think...
