It's possible. Sony didn't exactly invent the DVD, but the PS2 was the first console to use it, and then other consoles followed suit after it. And yes, I do know that the original XBOX used the DVD as it's disc format, but still. It seems like whenever Sony uses a certain format in their system first, future consoles adapt it. Although Sony could be stingy with how Blu Ray is used by Microsoft, seeing as Sony had a hand in developing the Blu-Ray technology, which they didn't do with the DVD.
