eh... True media hub potential, indie developer support and promotion from PSN and live arcade, online play becoming standard and a necessity, the massive push for creation and user generated content, and as much as I personally hate it, motion gaming? I feel like we've probably taken the biggest jump in the history of consoles this generation, other than the advent of 3D environments in the PS1/N64 era.
I don't think consoles are going anywhere. It's a matter of comfort and convenience. My consoles are where I'm comfortable, where I entertain, and where my family is. A desk is nowhere near as comfortable as a couch or lovesac (amazing, highly recommended, buns in comfort forever) sitting in front of a big screen TV. I feel like I'm hiding from the rest of the house in a computer room. Yeah, I know I could hook a tower up to a TV, but I like the division. Most things I do at a computer, but when it comes time to relax and game or watch movies, I want to move over to a giant sac of foam. To me it's like arguing that TV's are going to disappear because monitors have better resolution and you can stream most anything now.
