I'll definitely be getting one. The battery on my 5 is on it's last legs plus I really want a larger screen. I'd like the 5.5" variant (if it exists) but with the physical home button I think it's going to be a massive device. I'll likely end up with a 32GB 4.7. I'm really hoping they finally move the base model to 32GB and ditch the 16GB madness. I've been with iOS since the 4S and don't see myself moving away in the forceable future.
Apple did a recall on some iphone 5 battery's.
Might want to check if yours qualifies.
