It looks to me Canon is having a hard time designing its speedlites line in the current landscape. Probably it's hard for them to design models that can justify their premium price, between brands like Godox that offer a cheaper line with most of (or all) the features once available on top-of-the-line Canon units for simple on-camera flash use (and multi units too), and pricier brands like Prophoto, whose entry level units are anyway part of a much broader system wiith many accessories to tailor lighting to one's needs, something that Canon always left to third parties.
It might be they try the video/photo combo - it might be the wrong move, as it could appeal just to a subset of users doing both at the same time.
Just I hope they don't imitate the Prophoto Connect - a remote control that needs a phone app to manage the connected units.
