That’s old news. Not saying it isn’t coming out this year. All signs point to yes. But to say invites will be sent next week with no information and basing it solely on code that is news from a week ago is fundamentally flawed. Because with your thinking then invites should have gone out last week when that news broke.
Nobody knows 100% when invites will go out, only Apple know that! We all guessing at this point, going off of past actions from Apple and so on. Apple could send invites out any day now if they want too, or for the first time ever they could wait until November and have the first Apple event in November.
With Tim Cook in Europe next week my guess is the event will be on the 30th, invites go out next Tuesday.
