So, perhaps the 925 is the Lumia that the OP expected to see. 127.5mm x 70.5mm x 8.5mm (smaller all around than the 920) and 139 grams (about 25% lighter than the 920).

I actually prefer the look of the 920's plastic body, and think that the 'premium' metallic thing of the 925 is like chrome bumper-bars, but each to their own.
