Honestly I think even they know it's a luke-warm update. I would only upgrade for the cameras at this point but then again, they are still only 12mp. Same form factor, ugly camera bump, and then software updates. YAWN. Why can't they figure out a way to get rid of that camera bump or come up with SOME better way aesthetically to present 3 lenses? It's just so messed up.
I think the battery life will motivate some that didn't otherwise plan to upgrade.
