At the 2008 SOE Fan Faire we saw a very cool Station Voice demonstration. Two players were chatting via the Station Launcher while a third called in from a cell phone. There's no sign of the cell phone feature yet, but spotted in the June 11 EQII Test Update Notes were these tidbits:
Dan Kinney, on the Station Launcher forums, confirms the good news:
"Yes, the Station Launcher is joining the voice party. We are working out the final details between each of the games - they each are just a tad bit different. You will have this before we get to Fan Faire." Since you only need a Station Account to use the Launcher, not a subscription, this could make for a very powerful chat tool.
