New compact cameras with big sensors

Recently several big camera manufacturers announced remarkable products. Canon released PowerShot G7 X, a compact camera with a 1" BSI-CMOS sensor (20 MP), very interesting 24-100mm F1.8-2.8 lens, and 'flippable' rear screen. The camera weights about 300 grams (with battery!). Panasonic came with Lumix DMC-LX100. This model uses 12 MP 4/3 sensor (double of 1" sensor size) with variable aspect ratio 4:3, 3:2, and 16:9. The sensor contain 15 megapixels but only ~12 MP are used in any given format. The lens specs are very interesting, 24-75mm equiv. F1.7-2.8, considering the size of the sensor used in the camera. It is also has an electronic viewfinder, not bad for camera weighting just 393 grams.
