"What are you gonna use it for" can be applied to all items on your wishlist. Just because somebody has some other wish, does not make it useless, 128GB is important and no one is going to force you to buy it, it'll be even better for you, cause it'll most likely push down the high capacity into a lower price segment.
As for my wishes. They are:
A real breakthrough in the camera department, something amazing.
2GB RAM
128GB storage, again I don't need 128GB, but I hope it'll push 32GB down in price.
USB 3.0
H.265 Hardware Decoding
aptX BT
I'm starting to save up for the next-gen iPhone. I'm currently holding on to my iPhone 4S still. The TouchID, better rear camera in low-lighting, and 64-bit A7 chip are definitely great improvements. But I need to get more than those before willing to upgrade, here are more things that I hope to be added onto the iPhone 6 next year...
1. Larger screen (4.5"~5")
2. Better front camera for self-portrait
3. Waterproof & shockproof
4. Thinner bezels
5. Earphone slot to be moved to top for improved built-in speaker performance
6. Black-gold iPhone color option
7. Even bigger battery to compensate for the larger screen
