Although no specific date.. but i think it should be soon as they should only leak information when its around the corner, not like telling abt HOME decades ago.. 

Let see when this happens

HOME is going to be overloaded for sure, but I'll have to look into this myself

home can suck my balls, however, being to voice chat across games would definitely be appreciated.

Ah, nice to know!

it look to me that they are wasting time on HOME.. it hasn't picked up the way they expected it and it is just simply going to be a black hole for adding resources and effort. So they should try not to put too much emphasis on it... until more and more games donot integrate with HOME... which will surely take some time.

I dunno, if they keep releasing new stuff like the new space, they'll at least keep people interested. I was just online, and I had about 7 friends on. Out of those, 4 were on home, 2 were playing games, and 1 was doing nothing. Usually, I see maybe 1 person on Home every few weeks or so.

As for the cross game chat, I'd love to have this since I play lots of sp games, but like to talk to friends.

The game launching for Warhawk was pretty cool too; I tried it with a friend and it put us right into a collection match where we annihilated the other team. =D
