This in Microsoft discussion because...? Unless you're specifically trying to look at this from Microsoft's angle, the correct section would be Gaming.
OK, let's look at this from Microsoft's angle then. This will make Microsoft's exlusivity effort seem less successful, but overall, I don't think this will have that great of an effect. Tomb Raider isn't a system-seller, and I doubt Square Enix can make it into one in such a short time.
As for other angles, they shouldn't be relevant to this discussion.
