Well I guess it could be appropirate to say that Minecraft will be dead in the next few years. It means that Microsoft could make Minecraft 2.0 exclusive to Xbox, and Xbox Only. Meaning that the once crowning PC version will be nothing but a mere memory.
Even if you played the PC version you may need to pay a subscription fee to play the game online resulting in more money being spent, and even when you do pay be ready for the Moutain Dew, Lynx and Doritos Advers slapped all over the place.
They'll start charging you to use Texture Packs like on the console versions, they'll disguise mods as "DLC" and force you to pay a large ammount of money for it.
To cut it short, they may say that other versions of Minecraft will be unaffected, but give it time. We'll slowly see the other versions being abandoned for the Xbox version. DLC and Updates will be Xbox first, and the others will have to wait months or even years.
There is no reason for MS to buy Minecraft, if you ask me I think its because they fucked up with the Xbox One launch, their getting desprate, buying as many IP's as they can to milk.
Keep playing Minecraft while you can, for it will see the last of its life today.
