I'm still not certain what your point or main argument is. Are you saying that Consoles are fine, growing, and will continue to do so in perpetuity despite the challenges? You're debating a lot of particulars, but I still don't see what the main point is you're trying to make.
But those hopping onboard are developing their content for a variety of platforms, not just the Consoles. Is that false? There aren't many console exclusive digital only games being made that I'm aware of.
In ten years, a game like No Man's Sky or Rocket League would be playable on Consoles, PC, most likely set top box, etc. By eliminating the big disc based type technologically taxing games, the incentives people would have to buy a $300 box up front get even less appealing, no?
But they brought The Witcher to consoles because that's where customers are today. And we're not talking about today, or even 5 years from now. We're talking long term.
One dimensional is not how I've been addressing this.
I responded to particulars only to impeach the soundness of your conclusion - which is very much a part of the format of online discussion forums, and I say that in a non-condescending way. If you want me to solidify that into a position, I think that the console market with two machines at $400 is smaller than last gen, no question. But I also think it's likely they will continue to outpace their predecessors when they start hitting mass market prices of $249 and $199, especially leveraging more emerging markets, as Pachter also predicts in the other thread. If Nintendo positions the NX as a compelling platform in the next two years, it's likely this gen won't compare as badly to last gen as many are predicting, although it will unquestionably be drastically smaller.
The time component of your argument is not lost on me; if anything, it makes your observations
more nebulous, not less. Your argument that console games will be available day and date on boxes people already own doesn't just hinge on GPUs matching power of the penultimate generation. You're also saying that they will have the heat dissipation and storage capacity to install and play them for more than a few minutes. And that Apple/Amazon/Google will invest in the multiplayer and support infrastructure to maintain them. And that developers will still invest in cross-gen development, which now requires separate teams and has generally failed to add significant sales.
Your scenario takes for granted that these interdependent developments will extraordinarily happen simultaneously. But there is an even bigger unaccounted factor: Sony/MS/Nintendo will utilize the same technology Apple/Google/Amazon will to shrink powerful components. When your landscape comes to fruition, and they're selling the PS4 Slim and Xbox One Arcade for $149 or $99, your speculation inverts itself, as the prospect of buying an Apple TV becomes more questionable than it already is in the face of Smart TVs, cable boxes, and Blu Ray players offering the same core, streaming functionality that is, of course, the main draw of those devices.
