The third F&F Beta patch has just gone live and it re-introduced the Public Game system as well as helping a heads up on the upcoming Auction House!
Official Blizzard Quote:
Diablo III Beta Patch 3 – v.0.3.0.7338
Public Games are once again available to players. To help us test this automated matchmaking feature, click on "Campaign" and then select "Public Games."The number of characters playing the selected public quest will now display in the Public Games menu.
I think they will see how the public games service holds up, many only for a few hours, or a day or two and if it's working well they will start sending out invites. So I'm on the optimist side and hopefully we'll see it this week. =D
I have my fingers crossed, but I probably shouldn't. My heart is saying "They'll pick you! You have a very oddball video card that they'll need to test". My brain is saying "You idiot, they'll never pick you! You don't have a WoW account, so you don't deserve it."
