Sure, and it could also come with a ham sandwich lul, but even if that's the case I don't think it enough to warrent being included in a direct especially when the main info we got in May wasn't. What would you be expecting them to say in the roadmap? Other than more NES games (SNES was not confirmed) and maybe more convoluted voice chat apps, everything else about the service would remain constant.
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.
They could say when you could expect Super Nintendo games to launch(early 2019 or sometime in 2019), improvements on stuff in the console with the online, outside of features already talked about.Nintendo is known to hold stuff back.
Plus it dosent need to be a direct only about the service.All this information could be thrown into a 30 or 40 minutes direct, and it could last 5 or 10 minutes.
