Err, yes all true, but one might also argue that this camera is a product for an older crowd who hate cellphones partly because they cannot even see them without their glasses, that this is a camera which will often be used on a support, and that using the mic jack to detect a focus lock and shutter press would have allowed Hassy to tick a box cheaply.
I own a very nice pair of $300 Bose bluetooth headphones, but the sound of films is always out of sync on my computer- where wired earphones just work. I find that I can tolerate a wire better than sound that comes half a second after the picture.
Newer is not always better if the guy writing the spec foobars the spec. Lack of a cable release is a mistake, not a sign of the times.

Designs are set in stone a long time before they ship. It was designed not to have a cable release. I would be surprised (and I often am) if the X2D or whatever had a cable release. You may as well ask why iPhones don't have a headphone socket, why computers don't have CD drives and why poker machines don't have handles. They are obsolete. Does it need an external shutter release? Yes, but it is and will remain done by software the same as everything else will be done in the future. There is more chance of having your phone with you than having your cable release with you anyway.
I regard myself as a laggard in technology. It usually works well. I read about new things but unless I really need it I don't invest until others have fixed all of the problems and the price has dropped 30%.
