To jump in on the storage debate, as others have said, we're in the minority of phone owners. My Droid Turbo has 64GB, and with an 'average' number of apps (4 pages worth in the app drawer), rarely delete photos (even re-takes), and a good chunk of HQ music onboard, only 40gb are used. These days, people use streaming music predominantly over downloaded music (which includes streaming from a personal cloud) and don't utilize that many apps. So, I don't think the population at large has the need for more storage space right now.
With Samsung making 64 standard, it could sway the market, sure. However, many companies will look at it as something that people don't want so there will be no need to offer it in a base model.
