MS is helping the development, isn't this a fact?Again, they didn't need help, the game was gonna get made one way or another. With or without MS' help. If MS "helped" to the extent you are suggesting I think this game would be MORE than Timed Exclusive. If MS put that much money and time helping develop the game than it would be considered (at least partly) THEIR project, and it wouldn't even be on the PS4 in the future.
Pretty much.
edit: from the same article posted earlier:
The deal also means Crystal Dynamics can tap into Microsoft's hardware-specific expertise to help with the development of Rise of the Tomb Raider, Gallagher said. From the start, Microsoft employees have shown initiative to help Crystal Dynamics with the project, asking things like "How can we help?" and "What do you need?," Gallagher said.
