Does anyone know if Microsoft is planning to introduce 64bit Windows Phone next year?
Since Snapdragon 808 and 810 processors are launching the next year it is very likely you will see a 64 bit device somewhere after the middle of the year.
As far as the iPhone 5S goes, 64 bit has made the 5S subject to crashes in certain apps and by the time 64 bit apps become common the iPhone 5S's hardware will have become very outdated.
So chill, 32 bit is more than okay for mobile right now.
