I'm waiting on the case, but I did speak to a customer service rep and they said I will receive one.
Weight wise I find the phone to be somewhat heavy, but you need to consider the tech inside. The charging coil, camera, decent sized battery, and solid polycarbonate case all add up to SOLID!!! It's not really heavy I guess, it PREMIUM!!!
As for the camera itself, I've read that the update for it is being prepped. I'm unsure of the release date, but Nokia doesn't tend to let their customers down. The pics I take all seem leagues ahead of what I'm used to on any cellphone I've owned so far, so I doubt I'll be disappointed.
