Microsoft announced a competitive war by poking his fans to ditch PS3 and get 100$ store credit towards Xbox One.
How it works: Visit your store, let us recycle your PS3, and get 100$ of store towards the purchase of a new Xbox One.
To the answer of this statement Sony announced: KEEP your PS3 and save 100$ by ignoring Microsoft and buying a PLAYSTATION 4. 
 Who offers the best option?  😉
