Agreed. Don't really see the need to have social media embedded with everything. I just don't see how gaming could tie into it, though it might just be the bad impression of getting spammed with Facebook notifications from their games.

Also, if Youtube is any indication, users will prefer to use usernames versus real names, especially if you're potentially interacting with people you don't know.

I assume (hope) it would be more like Blizzard's system for Starcraft, which only lets you see the real names of friends that you add using an email address (and if they accept). Showing a person's real name to everyone in game just sounds insane.

This is exactly how the PS4 real name system works. You have to add a friend as a "real name" friend, and they have to add you back with the same permissions. Just adding someone as a friend doesn't grant them permission to see your real name.
