Good News everyone !!!

In the meantime, some new features may start to show up in data mined information for patch 2.2.0 that will not apply to all regions. Specifically, the following features will not apply to the European region:

A new currency called "Platinum"
Timed experience boosts
New cosmetic items including wings, non-combat pets, and character portraits
References to stash space and character slot expansions
A new UI interface that references the above information

While the above features will not apply to this region, players will still benefit from some of the quality of life perks tied to these additions, such as a streamlined UI for selecting cosmetic benefits like pets and Collector's Edition wings.

We recognize that many players have expressed an interest in microtransactions being added to Diablo III. While we may explore this model in some regions, we have no immediate plans to implement such purchases anytime soon for the European region.

These won't apply for Americas region either.

I wonder whether this currency will be exchangeable for items by trading, but I doubt it.

These features will likely come to the America's, but the Cosmetic things will probably be the only things that remain on the store for real money. People in America get pissed at companies and really don't like when they do micro-transactions. In Asia, on the other hand, people actually like the micro-transactions. I'd assume we'd get the features but they'd be obtainable in some other way. Just my guess.
