1. Because by the time the PS5 launches most people that by consoles will have a 4K TV and they will only get more common over the course of the next generation.

2. Because having a lower teir console will keep developers from getting the most out of the more powerful hardware.

3. Because it would complicate the market and Sony would have to produce two different systems for what would likely end up being similar total sales numbers.

4. Because if they can offer the more powerful hardware at a reasonable console price then why bother making a weaker one?

Sony litterally said this was why the Pro was coming out. Because near the end of the generation hardcore gamers tend to want a more powerful system, so they made the Pro to try and keep them in the ecosystem.

Good points there.... can't argue with the fact that all you have said is actually "possible".

But I still think its highly unlikely though.

This isn't really the natural evolution, but a forced evolution as a result of increased competition in the marketplace.
Microsoft placed a heavy emphasis on PS4 winning due to power differences. 360 won its gen for a long time due to performance differences as well as price and coming out earlier.

There is a very weird business mentality that coming out first, and having the best value, is what wins a generation. This is of course a fallacy because it's actually the games that win the gen, but nevertheless, both companies (sony and MS) knew that a generation was going to come sooner than normal, and so the reaction was to create a mid-gen console upgrade in order to stay competitive.

It sucks for console gamers to have to deal with something like this, but when you're up against a giant like MS, you gotta be prepared.

I agree.

Consoles are moving towards the mobile scenario.

1. Launch console A that is power level 1 at $399.
2. Launch console B that is power level 2 at $499.

- wait 2 years -
3. Launch console C that is power level 3 at $499.
4. Lower price / rebrand A at $299 and B at $399.
rinse / repeat each year or 2 years

why?
1. You build a true ecosystem of hardware and software. Say good by to droughts!
2. There is no longer an issue of BC as you would naturally continue supporting for several iterations of consoles.
3. There is always a new hardware you could purchase at several price levels that allows play-ability of nearly all games in that ecosystem.
4. Significant reduction of costs associated to new console generations as all tooling is continually and gradually improved vs fully rebuilt.
5. Can increase monetization of hardware through upgrades, subscription services, etc.

Supporting two HW models well is not as easy as flipping a switch.

If you want multiple HW models from day one, expect to pay a higher price overall. Consoles can deliver the best value by concentrating on one hardware design that can quickly be cost reduced by selling in large volume. Lower volume per model, higher R&D costs to design multiple models, both models will be more expensive or less powerful overall.

Although it does seem that the pro revision is a tiny bit further ahead on the power curve at release than the ps4 was at launch. PS4 launch, best gpu did about 5tf (gtx 780 ti), factor 2.7 faster. PS4 pro launch, best gpu did about 11tf (gtx titan x), factor 2.6 faster. Yet still the same cpu and memory.

They would have more profit by not making another .5 console that's redundant. The reasons why they made .5 home consoles in the first place is because of 4k TVs and VR.  If it was a good idea, they would have made .5 home consoles awhile ago. 

Its great I get to own a PS4 at launch and buy a better Xbox later and then go to PS5, play all games across all platforms and get improvements left and right. As long as both companies do it I will just hop back and forth between main console lol

Anyway, its just options as long as launch owners are not hurt in a bad way, which isn't happening to Xbox One or Ps4 owners, its all good. I would have liked to have a clearer roadmap like Xbox did by announcing the next console way in advance to avoid buying a console just to find out there is a better version around the corner.

The bestest thing:

PS5 utilizes all its power budget for 1080/1440p gaming so we get the best possible graphics and effects. The Pro which would cost $200-300 more would allow for higher res/fps gaming. Hell gimme dat $999 PS5 Skynet with all the bells n whistles.

Everybody wins.

I want a $750- PS5 pro with all the power they can stuff into that console.
