They said summer, so one would expect August at the latest. Since Square usually does push these as late as they can go, I'd just assume the last week of August. But given the bizarre hesitancy when he said it originally, I wouldn't be surprised if we weren't waiting until September. Well, I say we. But I don't mean me.
One must wonder what fate will befall this game during the interim. If everyone leaves to play other games, will there be anyone left in this game to play with? It's doubtful. But it is what it is. In either case, I'm glad we've been able to establish that a 7-9 month wait time of 0 content in a subscription game is fine because somebody somewhere has had it worse in another game entirely.
