According to Microsoft's Major Nelson the Xbox One will have 'more security on multiplayer games' than we have seen on any other consoles.
Major Nelson answered a question on Reddit when a user asked him if there would be better security on multiplayer games now that Microsoft has a matchmaking system in place for developers.
Yes. We've taken a lot of what was learned from Xbox 360 and applied it to Xbox One to make the overall online experience better," replied Nelson.
Major Nelson obviously didnt go into much detail on the subject, but he did say that Microsoft had learned a lot from the Xbox 360.
"That's all I can really say." said Nelson.
I guess we wait until next month to see whats changed.
