Pebble has just unveiled its latest smartwatches, and has done so in the most Pebble-like way possible, by launching a new Kickstarter project. The smartwatch maker has returned to the platform it used so successfully with the original Pebble, and the following iterations, with a true second generation Pebble and a second generation Pebble Time along with an all-new 3G wearable called the Pebble Core.
