Apple will already have the Plus model ready to go for next year. In fact they had it ready to go last year.
So next year:
Surprise surprise an X Plus
More anamojis
A12 super dooper bionic chip
Better camera
That will be 2018's new features, the Plus model being the killer feature which will take up 50% of the keynote.
If you got a bunch of snails to educate themselves about smartphone technology, they would be in a position to build a smartphone which is more advanced than the iphone by 2040. That's how slow Apple moves.
Of course we can't send them a message in the loudest way possible, that is, don't buy their products until they lift their game, as there are millions around the world who would by a turd if it had the Apple logo on it, so Apple will keep things which should be on the device now up its sleeve for a few more years so it can keep making $$$$, and thus those who want Apple to go back to being the innovative company it once was, start looking at alternatives which actually do more and work as well.
Steve Jobs was a technology man, not a dollars man.
Tim Cook is a dollars man, not a technology man. He probably couldn't even screw in a lightbulb.
And that's why Apple has become slower than a snail and that's why X did not come in the Plus size this year.
