Let's remember that he said this before the potential acquisition. I can already see people blaming Sony for them releasing a mario kart clone down the line.
Bring us Armored Core and Tenchu sequels built on the latest technology from other directors at the studio, but also an all-new RPG IP of the caliber of Bloodborne and a survival horror game both straight from the mind of Miyazaki himself.
IIRC, From Software was working on a game that where magic was the most utilized form of combat rather than melee or ranged. Need to see if I can find that rumor. Haven't heard anything about it since.
