I said this a while ago, if a 50 dollar price cut prevent people for going to XB1 it is worth it for Sony. I mean they literally get that money as soon as they buy PS+. Once they are a few games in Sony has made a ton. Add in all the movies and other content people could be using one lost sales could = hundreds of dollars (close to thousand if PS+ sub) over 5 years multiply that by millions....

360- 37 million Should trend down slightly after 3rd year peak
