Well I was going to point you towards the HD collection sales but VGC has fucked them up so lets just look at another big PS franchise gone multiplat

2 | Final Fantasy XIII-2 | PS3 | 2011 | Role-Playing | Square Enix | 0.78 | 0.72 | 0.89 | 0.27 | 2.66 |
3 | Final Fantasy XIII | X360 | 2010 | Role-Playing | Square Enix | 1.23 | 0.66 | 0.01 | 0.20 | 2.11 |

5 | Final Fantasy XIII-2 | X360 | 2011 | Role-Playing | Square Enix | 0.36 | 0.29 | 0.02 | 0.06 | 0.72 |
6 | Lightning Returns: Final Fantasy XIII | X360 | 2013 | Role-Playing | Square Enix | 0.12 | 0.07 | 0.01 | 0.02 | 0.22 |
You cant tell me something like this sales wise wasnt worth it. I dont expect the same thing from MGS but MGS appeals to the Xbox demographic more than FF does. MGSV on Xbox should preform quite nicely.
