What a waste of hardware instead they should be working on the next gen of the ultra 2.0 with a better camera with flash a new CPU and smaller Basel. Come on sony that is lame
They are definitely working on the Ultra 2 as we speak. It doesn't take a week to develop a new device. It takes a looong time. Do you think a device is finished when it gets released? No, the device itself is finished long before release. They have to manufacture hundreds of thousands or millions of devices for the release day, and that takes time, so they probably started with the Ultra 2 some time ago. They have to design it, they have to order up parts and components for that specific device, they have to test it for long periods of time. It's not done in a week.
The average time it takes a small team to develop a native app? Everything between 4-12 months (depending on its complexity), and that's just code. Now, how long does it take to make a physical device plus software to run on it?
