Pretty much all of this.

And that last point, remember the last time we all talked about the XB Two? Yea me neither lol.  Just news about the PS4K became so overpowering.

This.

Firstly a ps4k with anything beyond just 4k media output I don't think is happening.

Remember Sony hasn't said ANYTHING about this, it's pure speculation or even corporate sabotage via social media and rumors. Social media destroyed the Xbox1, these days Microsoft has a horde working for them in the social media circle.

Pushing 4k media is in their best interest since they sell 4k sets and media. I mean I can buy sub $100 android boxes that will push 4k content, the ps4 really should have been able to as well at launch, it's just a testament to how long before release the design was complete.

The constant noise that the ps4 is underpowered, really is irrelevant since this kind of talk from the master race has always been coming out of the peanut gallery.

Now one console being underpowered vs another of the same generation, that's something that's always going to be exploited since people are still looking to buy and want to know what train to get on.

Short console lifespans or mid generation hardware upgrades that split gaming specs will destroy the console market.

If they (the manufacturer) and the consumer really think this type of future is nessasary they need to bring back the cartridge slot. Go to a hybrid cartridge disk format. Where a developer could release a cartridge along with a disk, with assets on both the cartridge and disk, even addition hardware chips on the cartridge.

Someone like Ubisoft or 2k could release a cartridge with an engine on it that then could be used for multiple titles, and only require a new disk.

They were still supporting two healthy home consoles during the lifetime of both.

To sell 4K TVs, the same reason they pushed 3D a few years ago to push their brand new fancy and expensive 3D TVs at the time.

Because gaming is a lot bigger now than silly console wars

Kotaku needs hits to generate revenue to pay for their litigation.

Aren't there plenty of people that haven't switched to 1080p yet? All this noise over 4k is premature. It's really too soon because people aren't exactly chomping at the bit for higher res tvs or content. It would be quite a gamble for sony to do anything with the PS4 hardware wise other than creating a slim version.

There is so much wrong with this post I don't even know where to begin. All you've demonstrated here is that you have absolutely no idea why video game consoles are made the way they are.

If there is a PS4K, It'll be a minimum spec bump at a minimum cost with a 4K bluray drive and an improved HDMI port to do 4K video output, and that is it. You will not see a easily noticable improvement to performance in video games, if any. There are many reasons for this:

• These are the most profitable years of a console. This is the point in the life where you introduce a cheaper sku at a cheaper consumer price with a higher margin. You do this because it's at this point in a console's life where the price gets below that pain threshold where you get most of your lifetime sales and thus most of your profits. Introducing a new higher spec console throws a monkey wrench into all of that.
• While it is true that introding a console with higher specs is cheaper than releasing a new console, it is still far far more expensive than producing an even cheaper version of your existing console. Not to mention you'll need to  develop and create new developer kits, test kits, and new developer tools to allow developers to take advantage of these new specs. This is one of the most expensive parts of console development.
• Video game developers, unless they are forced to, will most likely not support the additional specs because there the additional time and money associated with buying new dev kits and developer tools, and all of the additional QA work (which would be practically doubled to support it), not to mention engine development and dealing with specification-specific bugs is a handful. All for what? There is absolutely zero reason to expect supporting the improved spec will lead to additional  video game sales. So at the end of the day, the vast majority of games will not take advatage of the additional specifications, which has happened every single time a company has offered a console or add-on with a specification improvement mid-generation.
• If developers are forced to support all specs then those costs will be passed on to consumers. I'm sure PS4 owners won't be happy to pay $5-$10 more than Xbox One owners for the same game, especially if they don't own a PS4K.
• If they don't force developers to support all previous versions of the PS4, the new console will start to get some exlusive games, older PS4 owners will feel robbed because they bought the PS4 expecting it to play all modern PS4 games up until the PS5 came out (just ask owners of the non-new 3DS how much they enjoy playing Xenoblade Chronicles). This will piss off millions of people if they bought a console for christmas 2015 and now new games are coming out christmas 2017 (for example) that do not run on their PS4. This is the kind of anti-consumer decision that made many people buy a PS4 over an Xbox One.
• With a small existing consumer base (less than 10% of HDTV owners own 4KTVs, and a small percentage of those are gamers) and little games that will actually support the additional specifications, there's little reason to expect this will garner the tens of millions in sales that the high margin sku would otherwise generate

The idea might look good from a purely theoretically "best gaming experience" possible, but it falls far short when injected with reality.

Upgradable consoles are not the future of the console industry. All that does is confusion and frustrate the userbase. The reason consoles sell the way they do is because a PS4 owner can walk into the store, pick up any game with a PS4 logo on it, and know it will play in their console. It doesn't matter if they bought their PS4 in 2013, 2016, or 2018. They know that game will work. They never have to worry about compatibility. They never have to worry if their PS4 is going to run the game at a reasonable frame rate. They never have to worry if the game on their PS4 is going to be buggier than their friends. They never have to worry if their friend with a new PS4 has a competive advantage in online games compared to them. You know, all of the things you need to worry about if you own a PC.

See here's the thing. PC gaming is arguably cheaper if you're smart about it. People buy consoles not because they're cheaper initially, but mostly out of the convenience over PCs they offer. If you want a "better gaming experience" in terms of graphics and framerate? Buy a PC. Consoles have never been that solution. There's no reason to expect them to now.

He does live in a work where specification improvements have always failed though. There's a world of difference between releasing a higher margin slim PS4 and a PS4K that's more powerful.
