The way I see it, the fact that Bethesda said no to Mojang giving them what they want means that the trial was never about name but about something else and they're simply using the trial to accomplish some other goal. Now that Mojang has made its legal, yet small, mistake, Bethesda could be using it as an opportunity to do something else.
The point I'm trying to make is, if Bethesda wins in court, what do they stand to gain? They may demand the IP that is Minecraft or even try to take the company itself. After all, the popular way to do business nowadays is for a company to consume several smaller companies and a few actual competent businesses so the company can grow a few steps closer to becoming a monopoly. That's what happened with the cell phone industry.
