There's not much left to talk about with the online service besides an exact launch date, we know the meat & potatoes already. Since it's a negative thing, I doubt they'd want to bring down the whole direct by including it when they can just continue keeping it low key.
Otherwise within two weeks is possible, as is anytime really lel. At the very least there'll definitely be one before the end of October to hype up their big guns for this holiday.
They could very well, outside of the few details that remains, release a road map for the service.For things like when does Super Nintendo games will start appearing, what to expect of the service until the end of the year, and so on.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
