Videos embedded in a Pages doc, playback in other formats?

My question

I presume that the video playback function only works in Pages or Numbers; meaning, if I produce a PDF version of my product I created in Pages and includes an embedded video, it will not play for someone viewing the PDF version using Preview or Adobe. Would my presumption be correct?

If this feature only works when the document is opened in Pages...

Is this in development? The ability to keep interactive media functionality in a static document format using any PDF reader, would transform what we create and share in this medium. It's no where near as useful if it only works in Pages, given this Apple product has not managed to disrupted the Microsoft monopoly on the currency of file sharing, even though it is a better product.

If Apple can make the video or any multi-media embedded in a Pages doc transferrable to PDF, it would equate with the opportunity to create a well packaged resource that is far more engaging than a standard PDF or report. We could embed data visualizations which would save space on the page. We could embed video created to provide examples or demonstrations that is less impactful in writing. While this sounds just like a webpage, I don't see it as the same. In a way, we have seen letters move from handwriting, to typed, to digital email, to interactive email (watch this, listen here, jump to this webpage, buy this now) To play a video embedded in the layout of a PDF created in the Pages environment would redefine the way we communicate and arrange our messages.
