Blizzard's official Diablo 3 web site announces a PTR (Public Test Realm) for the popular action RPG. This, of course, coincides with the developer's next update - 1.0.5 patch.

Here are the 'General' improvements (read the full patch notes here):

• Resplendent Chests will now operate similarly to Elite packs in Inferno difficulty:
  • When players open a Resplendent Chest, they will receive a reward based on how many Nephalem Valor stacks they have active at the time
  • Opening a Resplendent Chest will grant one stack of Nephalem Valor
• Major in-game events will now grant one stack of Nephalem Valor when completed by a level 60 character in Inferno difficulty If completed in a multiplayer game, all eligible characters in the party will receive the buff regardless of whether they participated in the event or were close to the event's location
• Major in-game events in Inferno difficulty that involve a special chest or Unique monster (ex: ) will now also drop additional loot for every stack of Nephalem Valor a player has active at the time of the event's completion
  • Several events have had Unique monsters added to them for this purpose
• Experience Shrines can now appear in Inferno difficulty
• Two new shrines have been added to all difficulty levels:
  • Empowered Shrine ' Increased resource regeneration and reduced cooldowns
  • Fleeting Shrine ' Increased movement speed and pickup radius
