I'd be surprised if they did do this. In this day and age of using the phone for shooting pictures, videos and lots of apps. Its kind of crazy not to make the 32GB model the base model, but I'm not holding out hope.
That's kind of why I was hoping for the increased storage on the base model. My 4S was 16GB and I had to clean it up once in a while due to iMessages filling up with short videos and photos, as well as the Photos app and Photo Stream taking up space.
I have a 32GB 5s now, and I'm doing very well with the added storage.
