It's true that it's not like DVD won a format war because of the PS2 (whereas you can really make that argument with Blu Ray and PS3). But Sony has a vested interest in selling more DVDs in a way that Nintendo and Microsoft (and Sega) do not - precisely the reason that the PS2 was the only console of its generation to feature the supposedly easy option of DVD playback (not counting that bizarre and shitty Xbox dongle). Similarly, Microsoft has a vested interest in keeping developers and gamers using its software. These are big companies with their hands in a lot of pots: both of their agendas for video games go well beyond making profits directly off the machines and license fees.
