That wouldn't work for Sony. Most people I know that own a PS4 don't own a single Sony game. They play GTA, Fifa, CoD, Far Cry and Overwatch. Maybe some Crash Bandicoot or Final Fantasy.
TBF I don't think it would work for anything besides maybe Mario, Zelda, Pokémon and GTA. Those are pretty much the only series that already see most of their sales at launchprices.
