As already written, I was also shocked about the 5.5" Screen. But I still hope, that the device isn't much larger than Jolla C. Looking at Chens renderings, it look's like he isn't planning a huge bezel. So making a device in the size of a Jolla C (or only a bit larger) is still possible with a 5.5" inch screen. Maybe Chen can say something about the planned final size of the phone, He already pointed out, that the phone should be around 12 mm thick, so I think he has already an idea about the over all size.
