So it will probably be only a financial upgrade for Sony so that they can produce it cheaper whilst it has no effect on the PS4PRO itself. In other words nothing worth mentioning for the customer. The vanilla PS4 also had these kind of upgrades.

My 1200 series PS4 is much more cool, silent and less power hungry than the 1100 version ...definitely very noticeable.

Fair enough but the pro is already pretty silent compared to the phat model. It is more often than not even more quiet than the slim when playing taxing games. While the og CUH1000 PS4 sounded like a jombojet at times. The only moment I can hear my PRO is while trying to take on 7 Glinthawks or a Stormbird in Horizon at checkerboard 2160p.

Looks like an internal update where the Pro uses cheaper and less power hungry parts.

Doesn't sound like an upgrade. Sounds more like a change.

PS4 Pro always looked like a very costed upgrade in the first place. They didn't go mad with an increased specification over the standard ps4, no UHD blu-ray or much extra in cpu power or memory. From what I've seen it was pretty much a design to get the max boost at the minimum cost and nothing more. This new revision likely takes that even further with a reduced manufacturing cost and possibly lower return rate and Microsoft will have to take huge losses on the 'X' to get close to the pro in price which they may be forced to do if Xbox sales continue to dwindle compared to ps4. I still reckon there is a good chance the original spec ps4 will be phased out in the next couple of years leaving only the pro model available. When the manufacturing cost gets very close between the 2 they may as well just drop the standard model.

I don't expect Sony to release another revision of PS4. Pro will be the last before the inevitable PS5.

Now bring the price cut.

maybe the new internal components is just cost saving to manufacture.

I speculated long ago, that Sony might choose to welcome the Xbox One X, with a price cut on the PS4pro.

This just makes that seem all the more likely.

PS4pro 349$ vs Xbox one X 499$, this holiday.... right?
