The post before, you literally used all three as examples of non shadow drops.
If they were, then that means majority of our announcements the last month and change have been shadow drops, and thusly, we are statistically more likely to get more shadow drops than we are to get any other information, making Smash even less likely.
I don't think it matters if something was leaked, as far as technicality of this conversation.
Ultimately, your statement initially was that 'the next announcement has to be about Smash,' a commonly stated comment, and that's just flatly not true. Hell, by the next announcement, it will be October and very possibly just a monthly partner update. If we get four more announcements and make it to November- then we know we have more Animal Crossing. Assuming Smash is next is just simply ignoring everything else we know about to some level, or know could come. There are many other options, and saying otherwise is part of the reason people get so restless 'waiting.'
