Has microsoft said anything on how xbox 360 players can interact with xbox one players? 

Like if i am signed onto xbl on my xbox one will i be able to see my friends who are on the xbox 360? or will i only see my xbox one friends? 

Could we interact with each other? xbox 360 with xbox one players.

If only we could all play games online together (for games that release on both platforms) could that be possible? xbox 360 playing online games with xbox one players? 

No information from MS that I can find.

It would have been awesome

I don't think you can. They are likely to be considered two different platforms.

As an example, BF4 won't be the same game between them. X360 will have fewer players and smaller maps.

Since Achievements carry over, I think friends lists will carry over too, and it makes no sence not to be able to see who's playing 360 when you're on One.

As for cross-platform gaming, if it exists, it won't be common. 360 games play cross platform with Microsoft published PC games, but I dunno. Hope for it, but I'm pretty sure games like TitanFall won't have cross platform play, since the 360/One version is made by a different studio. However CoD Ghosts might have cross platform play, to keep the player count high in the One version.

I hope they do that cuz i have friends that wont get the One at launch. I will buy multiplatform games on xbox one from now on. 

Like me!

If Titanfall doesn't get ported to the PS4, I'll likely pick up the 360 version since I'm not going to get a One until maybe 2019. I still want to own the console, some of its exclusives will be cream of the crop, and that's the type of gamer I am.
