evleaks has provided some details about next Lumia Flagship codenamed “McLaren” coming to all three major US carriers. Now, we can add some details about this device from what we have heard. For one, it is being tested globally which means in India too and here is what I could learn about this device,

Lumia 1520 like design language
5.2 inch Display
Will come globally as the next single Lumia Flagship
Snapdragon 805, Adreno 420
2K display resolution (2560 x 1440)
Windows Phone 8.1 GDR2
To feature hover based interactions termed as 3D-touch, which explains that earlier leaked Goldfinger and McLaren may be the same device

We assign a high Mill-O-Meter score of 80/100 to this tip.

We have earlier reported that Windows Phone 8.1 GDR2 may bring Snapdragon 805 and 2K resolution support and also RM-964 was caught getting tested with a 5.2 inch display. So, this sounds quite feasible!
