I have been thinking of getting a PS4 (planned for autumn) as it is beginning to have some interesting games & VR. If Sony does not kill these kind of rumors before or at E3 my interest will disappear!

1) no smart phone by 2024 will be close to what a PS4 can do today.

2) sadly you might be right, if we keep buying more and more expensive smart phones, they might become the new home consoles of the future.

Maybe by 2024 we ll have mobile phones we can put in docking stations, that ll be as powerfull as todays PS4.

The thing is, this does not affect your original purchase. All PS4 games will be compatible with PS4 and PS4 Spec 2. You will not have to go out and buy a new console, in fact the time between buying consoles should become even greater.

The only reasons to buy a PS4 Spec 2 are;

1. You have yet to buy a PS4.

2. Your OG PS4 breaks, gets stolen, lost in a storm, etc. 

3. You want the best possible experience and buying a slightly more powerful system is worth the slight upgrade.

It is as simple as that. The games on PS4 Spec 2 are not going to be any different than on the day one PS4. The only difference will be frame rate, resolution, lighting textures, etc. You won't see 64 Players on PS4 Spec 2, and 32 on OG PS4. This is not PS3 to PS4, it is PS4 to PS4+.

This is a great thing for the console industry. It is going to lengthen the life span of the consoles, and it is going to keep them fresh for people joining in years later, and give the core audience a chance to upgrade to better experinces, and not have to wait 5 to 7 years for even minor tech advancements.

As I, and others said above, hopefully this is only the first of at least two major PS4 revisions. I would like to see a PS4 Spec 3 around 2019 or 2020, as tech will still not be ready for a PS5 at that point, but we need something that keeps up with the rest of the tech world. 

Early 2019 will not be, because now is Tradition to release a console on November.

4. You will need to purchase the 2 Models because one will have a Lot of Bugs, other will have more games than the previos, and in some games will not take advantage from the Extra Power, and will look the Same thing.

PS5, don't need to be 4K, if Released in 2019, that is a Normal console Cicle 5-6 Years, after 5-6 Years will Release PS6, with 4K Gaming.

ok, so if you managed not to be interested in buying a ps4 until about 2 years after it was released, why are you worried about a possible upgrade now?

just do the same, stay on older tech for 2 more years after the new one comes out and then buy something you like.

Lool the way you speak here is like a console'S HW live time is 5-6 years( it can be 25 year if you take care of it lol) just joking. since it is  the company's support of that piece of HW,  in this case a PS4.5 will noway hurt the ps4 LT Support which means there is LITTERALLY NOTHING wrong with a release of a better ps4,  they will use the same damn discs. If someone has money to spend for a new Ps4 (like a new iphone6S) then buy  it if not stay with the old one, there are poeple out there who wait a console to be sub 200$ to buy it, if we wait for that kind of poeple we will have to  wait 10 years for a next gen HW lol

BUt seriously I don't understand the hate of a new ps4, it is like ask AMD and Nvidia to wait 5 years to release a better Graphic card. Since all PC use the same game, it simply doesn't make sense imho

Clearly the biggest problem Sony are going to face when launching the PS4K will be one of messaging. Stop people thinking it's splitting the userbase and they're onto a winner. The messaging for VR is going to be tough too. Sony have a LOT of marketing to do this year.

4. This is not going to be an issue. PS4 games will continue to run in 900-1080p and 30 - 60fps. PS4K games will most likly be 1080p/60fps or 1440p/30fps and upscaled to 4k for those that have 4K TV's. This is important, because it takes 4K TV's a lot of time to do the upscaling, and means their are response time issues, with the upscaling happening on the console, that issue is negated, and that enhances the experience.

As for PS5, well it has to be a signifigant improvement over PS4. That is not going to be possible for some time, unless people are willing to pay much more for consoles. By 2019, the CPU, GPU, RAM, and SSD tech will not be their for a $400 box that has a generational leap over the PS4. That is why these incremental upgrades need to take place until, the time which tech has reached a point where shifting to a whole new platform brings a completly new experience.

This is definitly going to be a major batle for Sony. Lucky, it looks like they are not alone. With MS and Nintendo following the same path, the whole market will be pushing the idea of tiered skus, and your content follows you. That is good for everyone. 

Then on the VR side, they have the benifit of Smasung, Google, Facebook, and HTC all helping demo the power of VR. Hopefully, this will lead to most people being able to experince VR in some way at various events throughout the year leading up to the holiday season.

Slightly more powerful is not enough for a decent vr experience. It has to be A LOT more powerful.
