But despite the changes, it's based on his inspiration, Jeb showed he can continue his work, but his own projects up until now aren't particularly impressive. So, if MS wants to keep Minecraft as Mojang main product,  everything should go fine, at least for a while, until natural saturation, but if and when MS will want to make a sequel, who knows?
Also, an essential part of Minecraft success is not being either greedy or domineering with users, giving them a lot for the little they paid, not milking them anymore after the initial purchase, and giving them as much freedom as possible. Will MS keep on behaving this way with them and resist the temptation to limit what they always received and what they can do with it or make them pay a lot more for it? Doing the wrong choice for short-sighted greed and control freakness could quickly kill Minecraft.

even if that is the case the main guys at the company have already said they are resigning, and one of them was the brain child behind minecraft so essentially they bought hte studio name and the ip and the IP is already hit its majority potential of sales.

There is a reason behind it that we don't know of. Maybe microsoft knows what the next IP will be and they decided to buy the studio so they can make all the money the next game will make.

Haven't read most of the thread, so apologies if I'm saying what others have said. Some analysts reckon MS is buying the user base "aka good will" as much as the IP. Apparently the user base skews young, which is a user base that MS has had a hard time attracting. It also seems like their plan for Minecraft is morenoriented to phone / tablet than to xbox. And of course windows phone is the one place Minecraft doesn't exist. So the strategy seems clear: bring a unique Minecraft experience to the mobile windows platforms thereby brining young'uns to the windows mobile platform early in life and get them hooked onto Windows. As the cigarette companies used to say "get them while they're young and you have a customer for life."

Sounds like a good strategy in theory. It will be interesting to see how it turns out. So many people already have Minecraft on one or more devices. It is a big ask to get them to buy another device just for, in effect, exclusive DLC.

If there's going to be a Minecraft 2 then that might pay off being exclusive to windows and Xbox. But it better bring something very new to the table. Mojang also was planning a new games, Scrolls, which may actually be the big prize. Being new and different, but hopefully with the Minecraft magic, could bring in a lot of new customers.

I think it's a 50/50 move. It could pay off big, or it could end up being another bad acquisition that has to get written down in a fee year's time.

Microsoft knows there is a lot of Minecraft players, so if they make a Minecraft 2 then it is sure to pull in some fans, and then there is Windows Phone, so they can make a mobile port of Minecraft 2..

I highly doubt people are going to be buying Windows phones just to play a port of Minecraft, or the theoretical Minecraft 2.

Yea I don't see the logic in them buying Minecraft, so I had to think of something.
