Co-host Jez Corden mentioned on the Xbox Two podcast that he had spoken with an Xbox executive at the Cologne Game Show specifically about bringing Platinum Achievements to the ecosystem. The executive said that Microsoft is interested in improving the achievement system.

Microsoft is currently focused on other matters, but they recognize the importance of enhancing the achievement system to provide players with more challenge and motivation.
It is noted that achievements can extend the appeal of a game and motivate players to do more than just pass levels, which are specific challenges set by developers for players. These achievements can align with the game’s main storyline, such as completing a specific game level, or they can involve secondary tasks, such as discovering hidden abilities or hidden levels. They can also be completely independent of the game’s main or secondary storylines, requiring the player to complete the game in a particularly challenging or unconventional way.
