A new developer update video for Overwatch discusses what to expect now that beta testing of Blizzard's upcoming multiplayer shooter has resumed. Word is: "Game director Jeff Kaplan discusses what the Overwatch development team has been working on since the Closed Beta went on break in December—including a new game mode, new maps, a new player progression system, and a variety of improvements to our Private Game feature." There's also a new Player Progression Preview to outline how this aspect of the game will unfold. Here's a bit on that:

To this end, we've added a brand-new player progression system to the game, which gives you the ability to earn levels and unlock loot to customize the appearance, sounds, and other cosmetic aspects of your heroes—and it's available to check out right now in Phase 2 of our Closed Beta test.
