I will pick mine up from cpw store in town whenever it comes in assuming weds or Thursday. I have the note 2 which I'm happy with so not wetting myself over this upgrade but still looking forward to it all the same.
As for batteries they are partially charged so I have a play and get the restores going and then stick it on charge while its installing apps etc.
Batteries are pretty bullet proof nowadays but I've never been one to faff around with magical mystical charging cycles. Never had any problems either.
