Bought Minecraft and a few other games on Xbox 360, will I have to buy them again if I buy an Xbox One?

Minecraft will not be 60$ that's absurd if anything you will need to rebuy it since you have played the version optimized for the 360 , it will definitely not be 60$ ( and will not be like the computer version , they will always be behind in updates , and servers won't be coming either so don't jump the gun on this one ) why would they charge you 60$ for a game that's always been under 30$ even for the PC version so making it like the PC would not double it's value for no apparent reason , in my personal opinion hold onto your 360 you know why? They are still going to release 200+ new titles for xbox 360 over the next few years any new game that xbox one gets xbox 360 will get for a few more years after they are out of titles , xbox 360 will become obsolete but don't worry to much just yet , your better off getting the new games on xbox 360 till they run out of titles then you can go ahead and upgrade when they have tons of exclusives for xbox one

Minecraft will be 60$ for Xbox one when it releases and btw only like 10 games or so are out for the Xbox one so yes if they are new games you will have to purchase them again but if they are old say bye to them because you can't upgrade them. Btw minecraft will be 60 because it will be a completely new game some people even say it will have servers like Pc.
