what tombstone? Only one these franchises is actually dead. Disgaea manmaged to make it up in overseas sales, NIS specifically saying thats the reason they stick with PS4. FFXV made more bank and sales than FF13, despite many people thinking the franchise was dead (I wonder where we have heard that before). Yakuza seems to have gotten a resurgence overseas with 0 and RE7 is on track to meet expectations.
I think you know what he meant and sales numbers are there to back it up.
2M -> 1.2M
170k -> 50k
600k -> 400k
900k -> 400k
I rounded up the number and was rather generous with LTD predictions for PS4 entries.
