I would like KH to do well, but I suspect it wont even get close to God of War sales.
KHs has sold ~24m units across Collections/Games+Sequels&Prequels/mobile&phone (all in all like 16 releases of KHs)
God of war is probably gonna do like ~15m lifetime sales, on just the PS4 alone... theres no way KH3 beats that (on just PS4).
