Sony is a *business* in a highly competitive market. They're in it to win it, long term. They don't want to just beat MS for a year or two, they want to secure dominance over them for the foreseeable future, perhaps drive them out of the console market entirely. That's why they made power plays to strike at Xbox's last strongholds. And like it or not, that's smarter business than investing in a bunch of brands that are only modestly popular in one region.
As others have pointed out, Nintendo would have been a better option. 60mil is nothing for them; they have billions they could spend if they were so inclined. And Nintendo has truly become a 100% exclusive focused brand in most people's eyes so increasing and further diversifying those offerings would make sense. Sony is the epicenter of third party console gaming; all these IP would have to compete with the major third party games that they share genres with (and that Sony has marketing deals for). On Nintendo platforms, there would be no such direct competition and Nintendo would be free to promote them since they obviously don't have marketing deals for third party games that would crowd out these games.
