Unless word of mouth gets really bad (not likely) MGSV should sell around 800k LTD, or more. MGS2 and PW both managed ~790k, while MGS3 managed to surpass 800k. I think MGSV has the potential to as well. Taking that into account, if the final ratio between PS4 and PS3 end up being something like 3:1, MGSV will easily become the best selling PS4 title in Japan with ~600k. That's both a great achievement for MGSV, and a sad reminder of how far this sort of console gaming has fallen in Japan. It's pretty amazing for Nintendo that Splatoon will probably be able to outsell MGSV on PS4+PS3 combined.... on the WiiU... in Japan.
