Yes they do.
A full game to all the pre-ordering guys even if it was in name only.
If they don't then we get refund. All in all it would their loss if they just leave the project unfinished.
I specifically remember a statement that said, "You are paying for the game as-is," when I purchased in Alpha.
No, they really don't. It's been stated numerous times that Notch could toss his hands in the air, sell off Mojang, and let Minecraft die with the rest of his legacy.
This whole thread is a moot argument. You're not getting the new Minecraft products for other platforms for free whether you feel you deserve it or not. No one would be tenacious (and stupid) enough to take him to court over it. There's no more discussion to be had.
Not sure why there's still an ongoing argument.
