This is a great move for the studio, because it means less development cost. Tomb Raider was never a big money maker so to cut cost and raise profits they go exclusive. They may release later on PC which is easy to do considering the Xbox is a Direct X platform the same as Windows. I watch the announcement and they didn't say only Xbox buy if they don't its not going to hurt the brand I am sure well will seem more Titles from Square Enix only on Xbox. If you think about it Sony dumped all that stock and Square Enix wasn't all to happy about it.
