After our disillusionment at WWDC I suspected that aswell, but an October release doesn't seem to fit that well into these new database model entries. Not only because new models in 95% of cases previously appeared weeks and not months after they found entry into the Eurasian database, but also because the listed OS (High Sierra) doesn't fit so well into an October release window as there'd be no reason for them not to ship with Mojave then.September event will be for iphones and apple watch and the October will be for the macs and ipads
On the other hand, it's hard to imagine new iPads with Face ID and without Home Button to be released without iOS 12, seeing as iOS 12 is pretty much necessary to control them without a Home Button as iOS 11 doesn't have the new gesture system for iPads yet. So I'm really not sure what to think. I mean this makes a pre-October release much more likely then we previously thought I suppose, but seeing new Macs and iPads before iOS 12 drops in September would be weird aswell, so I don't want to be too optimistic about this either.
