I've heard a lot of people say over the last week or so that "if there is a PS4.5, that they are out of console gaming".

My question is: Why is that so bad?

You'll get to keep your games and have them enhanced each time a new iteration is released and all the peripherals e.g. controllers, VR, racing wheels etc. will no doubt be compatible. It will lead to companies focusing on making new games and not wasting resources on HD / remasters and give people a long window to upgrade.

It also rewards people who already had the previous model through scrapage or trade-in value.

I think it is pretty exciting to possibly have more power available to give a better experience an a higher end option for PS enthusiasts.

I don't care about graphics. I buy consoles because I don't want to worry about hardware and stuff. I just buy the damn thing and I'm good for at least five years. If they beef up the specs, sooner or later there will be games exclusively for that new machine, forcing me to either miss certain games or buy new hardware. That would piss me off.

If I wanted to think about hardware and upgrade every 2 or 3 years, I would just get a PC.

The 300-400€ you need for another console is a start.

You still do not have to worry about hardware unless you want.  When a new graphics card comes out, do you worry that the games you play will stop working.  If you are comfortable with the hardware you have do you upgrade.  If new games and old games will still work with the investment you made with the existing hardware, how does this hurt your current investment.  

The type of hardware change MS and Sony are talking about will not suddently make your current hardware obsolete.  Actually faster hardware would not make a difference as long as the base unit does not change.  Developers will do what they do on the PC.  Code for the lower end system first to make sure everything runs on those systems and give options to run better for the newer hardware.  It would be stupid for developers to not make sure the current system run great since theire are way to many systems to ignore.  

Because in reality it rewards no one.

Because in reality developers will always develop in the most affordable way possible - for the lowest common demoninator, which means either the PS4 or the PS4.5 do no get the attention they actually deserve without driving up development costs, and you cant possibly expect developers to spend more money when there is little to no chance that extra effort will lead to more sales. Developers will also suddenly have to program online play to account for the hardware differences. Which means 99% if ganes will probably not take advantage of the additional performance for anything other than things like load times.

Because in reality it means that everyone that bought a PS4 expecting developers to give that console their best efforts for the next 5-7 years suddenly cannot count on that any more.

Because in reality developers might choose to make games exclusive for the PS4.5 which means that new games that consumers thought would come to their console actually might not come at all. If this happens this effectively means that their console might quickly become redundant a lot sooner than expected.

Because in reality this segments the userbase. Period. Nobody wins.

Don't believe me? Just look at the New Nintendo 3DS. There is ONE game that actually puts the extra performance to good use. That game was developed and published by Nintendo and is not backwards compatible with the 3DS. Also, you want to play new Super Nintendo games on your 3DS? Ohh too bad. They're only available on the New 3DS. The fact is, from this point on, any gameor feature or service  Nintendo announces for the 3DS its fanbase has to wonder if that means all 3DSs or just New 3DS exclusive. Is that a question you want to ask yourself as a PS4 owner?

Because I don't. And I don't think any other PS4 owner that doesn't have a PS4.5 wants to ask themselves.

As long as they don't leave the current PS4 owners left out there shouldn't be any harm. Unlike Nintendo with their 3DS.

I bought 2 ps4 already, having to buy another, it is a annoyance. If they wanted 2 versions, those should be there at the beginning. Want to do that for ps5? Sure, go for it, i would buy the more expensive one with better specs, but now that I'm already committed to this one, it's just a bad move imo.

From consumer POV, I don't see anything wrong with releasing half cycle (every 3 years) an upgraded model, as long as the older model is fully supported and .5 model is halfway to next gen (in this case, that would mean 3x PS4, or something like 390-390X for GPU).

From Sony's POV...honestly, I don't understand why would they go with PS4.5, unless it's only for 4K media and not upgraded CPU/GPU. If they are upgrading CPU/GPU to run games in 4K with same settings as 1080p version of PS4 games they need (real life tests) 3x GPU...and that sort of power on 28nm is not something they can cram in PS4.5, and we're yet to see any 14/16nm GPU in the wild, let alone APU.

It would piss me off in a Level so High that i would never play on any Console Again, Microsoft, already confirmed it, but Sony, has yet to announce if it is a Slim Version, or if is indeed a Hardware Upgrade.

They should bring an upgrade in 3 years and call it ps5.
