They only need one big win. If they manage that, the rest would be much easier. As arguments will have been made and ruled. They can refer to the case against Google as precedent, making the subsequent court cases short, cheaper and/or not be necessary. If Google loses apple, Microsoft, Sony and Nintendo will all examine changing policy or settling any disagreements earlier.

I mean don't get me wrong, it's absurd how locked down their stuff is, but I'm not aware of prison time for opening up consoles yet. You can get sued, like Sony vs Hotz, and get ordered to pay some outrageous restitution, but that road ends in bankruptcy, not prison. Still complete bullshit that they can bankrupt a person, but there's no prison....yet.
