By pretty much the same line of reasoning that Bob uses ... you can say Consoles are Dying as well.
I mean, what defines a console?
The controller in hand? That's going with new motion controls.
The box by the TV? Cloud gaming / streaming will take care of that old device.
The sitting down on the couch to play? Where and how we play is expanding.
Even the TV itself is likely to evolve as it always has been, getting bigger, more high def, more immersive, more pervasion, less intrusive, more ubiquitous... it's crazy.
Of course I don't believe any of it... people will always re-cycle terms like 'PC' and 'Console', redefining them to mean what they want them to mean.
Saying a particular technology is dying, is as stupid as saying TV killed the Radio. Sure, there are trends, and money moves, but it's rare for technology to actually die out, making the semantic use of the word 'dying' to describe what's just a downward trend, somewhat inappropriate.
