Regarding platform choice,
In order to unify our ONLINE players and audience for the first season of a brand new league it was decided we would choose one console platform for NA/EU.
ESL, Warner Bros., and NetherRealm spent a great deal of time researching and deliberating what would be best for an ONLINE league, culminating in a live finals. After months of meetings it was decided to go with the Xbox One for NA/EU for a variety of reasons, including:
The track record of support from Xbox for competitive leagues.
The robust performance of Xbox Live.
The ESL App on the Xbox One.
Was it an easy decision to make? No. The casualty of the console war is a split audience and player base. We knew that any selection we made wouldn't please everyone.
Do I feel we made the best choice for an ONLINE league. Yes.
In regards to questions about 'Will we have PS4 and PC (outside of CIS/Russia) as options in the future?' Let's make it through Season 1 first.
The Sub-Zero Blue Steel Skin will be available across all platforms. Those purchases support the entire Mortal Kombat X Competitive Scene, no matter the platform
