Ninja Gaiden 2 was also published by microsoft in a similar fashion. Much like Spencer admitted hey had no answer for uncharted so they published tomb raider. Ninja gaiden was supposed to be their hack slash for the Xbox (only to lose exclusivity of it a year later).
They really need to learn how to make their own ips. I will enjoy tomb raider but this is twice now. A third time and they are making it blindly obvious that they can't make aaa ips on their own. Next year sony has the momentum...and their first party generally starts picking up during this third year. Time to get moving ms. When the third, second and first parties start to mount the natural ability to create ips will become noticable. This time it will be even more noticable since sony has vowed to make less ips this gen.
