Is it even worth 2 billion?

Minecraft has peaked long ago and I dont see much more money in simply rehashing it or adding more dlc.

Incredibly foolish if true.

What does that have to do with anything. Microsoft didn't create Bungie either.

Or was your point that these are famed developers that didn't start out with their respective console parent? Well Bungie doesn't belong to anyone now.

So... hypothetically, what would happen to the iOS/Android/PS3/4/V versions? Would Microsoft have them shut down, or would they simply cash in on the success of other companies?

I think they would get rid of the PS4/V versions and keep the rest, along with releasing a version for Windows Phone. After that they will release updates for Xbox and Windows platforms first, then ios/android, while leaving the PS3 version to fester.

Why get rid of two versions but not the others?

It makes hundreds of millions per year on merchandising and they can always make sequels/expansions.

PS4 because it's current gen and offers the most competition to MS, PSV because it directly hurts Sony as it's part of their current gen plan(remote play and such). PS3 on the other hand is an existing install base from a pretty much dead race and easy money, sell the base version with some add ons but keep the majority exclusive to the Xbox brand. ios and android versions are too much of an income to drop but they can be given a tier 2 release schedule.

Well if you actually read my comment, you would notice that I said they don't have the divisions to take advantage of this. I did not say *ALL* they would do would be making games. 

Grats to Notch if this deal it true. Best selling game of all time. I dont play this game but still

Microsoft sure love wasting money. Why not invest that into Rare and bring them back to their former glory?
