So not only will my PS2 disc do nothing, but the second digital copy I purchased on PS3 will also do nothing? That is incredibly disheartening. This feels like the danger of Sony having a majority share of the console market again. If they were down, they would have played this hand very differently, but unfortunately the mindset seems to be, "We're the market leader, so we don't have the need to be consumer-friendly right now."
What's most surprising is the stark contrast between this and the way that Microsoft handled 360 compatibility just this year.
