"Capcom has received a one-off royalty payment of two billion yen under the Digital Contents business from a deal for one of its IPs. The information was part of the Japanese version of the financial results. When asked by investors to explain the one-off income, Capcom executives refused to answer the question, citing confidentiality." - https://www.playstationlifestyle.net/2019/08/03/capcom-financials-aug-1-2019/
Capcom has received $19m dollars in some confidential deal related to one of it's IP's. While neither the IP in question nor the Company who paid the money has been confirmed with a PlayStation announcement at EVO imminent, could PlayStation be extending it's Street Fighter Console Exclusivity deal? Street Fighter V Ultimate? Street Fighter VI?

Other ideas for what it could be:
New Dead Rising - Dead Rising 3 was exclusive to Xbox One, Dead Rising 4 was a one year timed exclusive to Xbox. A similar deal perhaps?
Monster Hunter Switch - Seems very unlikely, I don't believe Nintendo would pay, nor do I believe they would need to pay for a new Monster Hunter game to come to Switch.
