Also a few more reasons:
- Xbox One runs a modified version of Windows 10
- Sony runs their private version of FreeBSD called "Orbis"
- Xbox One is both a console and a dev kit in one
- PS4 dev kits cost between $800 and $2,500 USD
- To get a dev kit you need a license from Sony
- You also need to be a corporate entity, you need to have a business plan for the game, and you need to sign some NDA's
- They do not have PS4 developers yet |
