So what are you arguing about? The original argument is that Sony would get rid of physical discs rather soon. With one suggesting they would do so eventually with a digital only PS4. Yet you even agree physical games will be around for at LEAST another ten years in your words, which actually crosses into next next gen.
You, and several others said this was a poor example:
.....said the person with a bunch of music CDs in 2005.
.....said the person with a bunch of DVDs and Blurays in 2010
My argument is that it is not a poor example. Physical media in the music, video and games business has not disappeared but from 2005 to today digital purchases have seen a very large percent of growth. The movie industry, not so much. The games industry, yeah there has been a lot of growth in digital purchases.
