Pebble's just shown off some of the new apps and games coming to Pebble Time and Pebble Time Steel just two weeks after the company released their Software Developer Kit. Because of the Pebble Time's 7-10 day battery life then the idea of gaming on the device itself isn't outrageous.
Pebble Time and Pebble Time Steel also come with a built-in accelerometer that provides support for step, swim, and sleep tracking with apps like Misfit, Jawbone UP, Swim.com, and Morpheus Sleep Tracker. No update was given on the Smartstraps as this ability, to add functionality by way of third-party straps is open to third party companies so these will likely be made available after the Pebble Time's May release.
