The specs are already out on Sonys website http://store.sony.com/webapp/wcs/sto...specifications
They offer a Wifi version for $269.
The good: 1280x720 at 120fps is going to make any video slowed 4 times to 30fps look butter smooth. 3 axis stabilization also compensates for roll.
The bad: 170 FOV is going to make any aerial video look distorted, no 1080p at 60fps only 30fps. And still photos are only 1920x1080.
The best part is that Sony being a major player means GoPro really needs to step up there game to stay ahead.
