I am in exactly the same boat, same upgrade date as you. I'm hoping I can get an upgrade next week, but I dunno if att will allow me to. I got the one x last year and I was burned badly. I tried to different HOx's and both had issues. I got a GS3 after taking my HOX back and it just worked and was everything the HOX was not. I liked the new HTC One in the store and i like the idea of Zoe, but I keep seeing post about Gap issues and camera quality issues, errors that require reboots or issues with unresponsive buttons and I am scarred to get it because of all the issues i had with the One X. Meanwhile, the SG4 is going to be a great phone, but I feel underwhelmed by it looking like a bigger SG3. But I do like the 13MP camera, bigger screen and i like it being on 4.2.2 among other things. I figure i will at least wait until the SG4 is in store so i can look at one and compare them, but i just don't know either. Good luck to you in your choice, i would be interested to see what you choose.
