Are Sony still selling new PS2s and PS3s? I think we can only buy them secondhand now, which means Sony already got whatever money they were going to get a long time ago.
Also, while the top sellers work reliably, unless something big has changed in the last year or so, plenty of PS2 games still don't work right in emulators, and even have game-breaking bugs. I have a large collection of PS2 games, and many of them are awful or unplayable in emulation.
This quote hits a little different when you know that Sega sells almost everything digitally for PC in the Americas and Europe, but virtually nothing within Japan and other selected countries.
They do not care about making their games available to customers. They care about profits. Overseas, the PC segment is big enough to be worth pursuing. In some countries it outstrips the console segment. But in Japan it's small enough that it makes more sense not to support PC, but rather to try to keep customers locked in to consoles, where they have tighter control and less competition.
