Thanks Xio-Feng for sending these in! A new Lumia device with a metal frame leaks out in images in China. Apart from the metal frame what is striking is the rear camera module design, which looks so much like Lumia 1020. So, these two (Aluminum body + Camera design) when combined together hint about an imaging flagship device.
So, are we having first look at the McLaren? McLaren is tipped to bring top of the line hardware like Snapdragon 805, 2K resolution display and will pack just a 5.2 inch display. It may feature hover based interactions termed as 3D-touch. It is also rumored to be the new imaging flagship which may pack more advanced camera hardware than Lumia 1020.
The two things which bring some doubts about it being McLaren, are its design and the camera without a big hump, though that may be due to Nokia being able to reduce the sensor dimensions.
