I'm wondering what sort of details Nintendo are hiding with their first party games post-Dread. WarioWare has had the demo and is now very imminent (exciting), and the rest of Nintendo's line up has had very little in the way of advertisement since E3. We've seen more of Diamond/Pearl, but we don't really know anything else about the rest. Obviously, the September Direct can cover things and there's plenty of time to get trailers out after that. We've also only just found out about Big Brain Academy, and Nintendo likely have more content coming (GB/GBC on NSO, Hyrule Warriors DLC, the final Smash fighter, Animal Crossing content, maybe some eShop games). Dread has thankfully had a lot of exposure.
Out of the remaining line-up, I'm thinking/hoping there's more to the Advance Wars remake than meets the eye. It's interesting Nintendo made the decision to package the first two games together and called it "Reboot Camp". I'm hoping that title is actually accurate and that this remake has some new content to pave the way towards new games in the series.
