has anyone thought in the future that microsoft shuts down the xbox network for xbox one...

Your question is quite valid, I believe that there will always be an alternative for the future so that you can run your games. We see a lot of video games that no longer have access to the store and updates and even so people still continue to use the games that they have previously redeemed or purchased, I can cite as an example the Nintendo Wii consoles, Nintendo 3ds, PSP, among others. There will always be a solution.

I dont think EA thought ME3 was going to be as big as it was. I dont see then shutting things down anytime soon. I mean they left sims 3 pets up for over a year and it was a broken game. If they shut it down soon how many people would not buy ME4? This thought
has crossed EA's mind. Support now for future sales later.

My biggest concern about the Xbox One is what happens during the generation after this upcoming one. During the 360 era microsoft shut down the original Xbox servers. Now if they do this in the future and shut down the Xbox One servers can I not play my
games anymore because there is no server to check in on? I dont want to feel as though I spend hundreds or thousands of dollars on games that I can only play for a certain period of time. It just makes be feel like its an extended game rental. Sorry if this
has already been discussed.

MSN Messenger got shut down since Microsoft now own Skype. Who knows, in the future the Xbox-360 may get an update adding Skype to it.
