This is the contract that was court ordered to be released when activision was sued 
Around the end of page 2 and the beginning of page 3 there is the subject of platforms the contract says "destiny #2 will be released to xbox 360 xbox one and personal computers running windows based operating systems" it's right there! 
Hope this helps
