No, it should usually look like v4, except in cases where you're using more address space and need to add more dots. NAT is here to stay, and a LAN doesn't need 128 bits of address space.
The :: only expands to fill all-zero hextets.
Oh and I'd actually prefer the 65520.
The huge prefixes allow for a simple hierarchical network structure and gives us room to redo the address scheme if we end up wanting to (only a portion of addresses space is currently allocated right now) without having to go through this entire upgrade the internet again.
As an end user who has a choice, they have to give me something that's not harder to use than before. I think they could have managed that if it were a priority.
