This invitation has nothing in it - intentionally - just like the this event has nothing interesting to show. Its just tiny updates to the air to get it up to speed with the iPad Pro and a phone with less stuff in it than the current. I dont see why this gets people even interested, or that Apple has an event for it at all for that matter. If any other company would have an event and show a smaller version of their current phones and a minor tablet upgrade to one of the sizes, it wouldnt even get a news headline.
