It will matter from day 1. No one gets excited for a system that's basically the same thing as something else that launched 3-4 years earlier?

Would you be excited about the smartphone that's as powerful as iPhone 5? Yeah it can run the same apps, but so what? 

This strategy only works if you have a groundbreaking, earth shattering, stop everything you have to try this type of other aspect to their hardware like the Wiimote was to the year 2006. 

PS4/XB1 is crap hardware by today's standards, even Sony is apparently making something double the PS4 for $400 in PS4K, you will have tablets as powerful as the XB1 at least quite soon. 

But I wasn't talking about the electricity cost, but the amount of heat that the components produce.

The PS4 and X1 use more than 100W while gaming (source: extremetech.com) but that is for the whole device: CPU, GPU, RAM, HDD and optical drive. With the 8350, just the CPU would already generate more heat that a PS4/X1, and you should have to add a similar amount for the rest of the console.

You can't put 200W of hardware into a shoe sized box and expect to run cool without big heatsinks and noisy fans, which no one wants.

Let's not talk about power consumption. I know some people don't care about that, but I'm always looking about how much I'm going to spend at home with each console. I have a small wallet :P. This gen it's fine, but previous one was a bit overpriced for my taste. It doesn't seem too much if you game a little, but on the long term is not that bad lol. 

OT, I think Nintendo could easily manage to make a PS4-like powerful console, and prized it 300-350 now. I just hope they don't include an expensive controller (as much as I like the Gamepad, it's made the bundle more expensive). Prize is an important factor on people's choice about a console. 

Speaking of the PS4K, if I were a PS4 owner right now,  I think I'd be really upset.  They buy a console with no real worthwhile exculsives other than Bloodborne on the promise that great exclusive games are going to come in the future and now that the time is near, Sony unveils a new PS4 that makes the one they already own look like a piece of shit.  The big spit in the face to me is that early adopters don't even have the comfort of knowing that they were able to play great games earlier than those that waited because a significant number of the notable games that came out for the first two years of the PS4's lifespan were cross-generational or remasters.  Aside from getting to play Bloodborne a year early, I don't think there were many positives in being an early PS4 adopter.  I'd imagine the anger I'd feel would be like how some Wii U owners felt when they started to realize that Zelda U was going to be cross-generational  -- except significantly worse.

At least Nintendo had the decency to release the n3DS when the 3DS already had years of great exclusive games.

Yeah, I mean, if you already have a component which consumes up to 100W, probably the entire box would consume more than 200W, and, well, you'll need a big box with really noisy fans. And it'll consume double the amount they already consume. Am I right? (As I said, not an hardware expert).

Actually, it has nothing to do with hardware but rather physics. It's the law of conservation of energy: "Energy can not be created nor destroyed, only transformed" (or something like that). 

In this case, it means that 100W of electricity = 100W of heat.
