So, something's been picking my brain lately. Earlier this year, I had an upgrade coming and was thinking of either the Evo 4G LTE or the GS3. The GS3 won this battle because it brought something no one else had before, 2GB of RAM. When my upgrade was available, I decided to wait for the Nexus 4, but, it seems like it won't be coming to Sprint. And so, I'll be waiting for the next wave of devices. The rumored HTC M7 has recently caught my eye. But here's the question.. Just to stir up some conversation, what upgraded spec/feature/anything do you guys think will be coming to the Galaxy S IV that will trump this (or any other) device in 2013?
