Retail gaming PC's? People build their own from what particular parts they fancy.
The problem with that argument, is that I see it the other way around. Every PS4 game (for the most part) will be on PC. What's the point, when the definitive version isn't even on the console. I look at exclusives, and what experiences are on a particular console that I can't get anywhere else.
And I disagree that having a weaker system means lower quality games, we've seen this disproved time and time again. It's up to the dev's to make the quality shine through.
It could be said that a PS4 is considerably more expensive than a Wii U, similar price differences. Don't forget Steam machines will be entering the fray soon as well. Should be interesting when that happens.
Does a DVD player or Blu Ray player enhance my gaming experience? Hell to the no. A nice additional feature, but can be sourced elsewhere for cheap nowadays anyway (I personally haven't watched a DVD or Blu Ray for years; streaming all the way).
Overall, my main point I guess would be that the PS4 and Xbone are stuck somewhere in limbo between the Wii U (most 'true' console of the gen) and PC's (the 'true' next-gen experience). The arguments made for the faux-PC's work for either the Wii U or PC, depending on which they're being compared to, but most seem to blind to realise.
