Oh yuck! I think the first point works in your design, but not the second. If a PS4.1 game is designed from the ground up for 4.1, running it at a lower spec would be much more likely to break it verse just lowering the framerate. It's like how a few weeks before going gold an Uncharted 3 dev took the disc home and tried it on his phat. In the office they tested on slims and everything worked, but on his phat the game was a mess and became unplayable after a few hours. That was just with super minor differences and it broke the game.

Of course if Sony did your idea devs would be testing on the weaker system throughout production, but it'd still ad another development hurdle.

The GOW video was a different situation anyway. It was an up-clock while this would be an increase in resources.

The difference all depends on how many system resources are currently reserved. So with the RAM if only .5 GB were reserved, then it'd be a really small difference. If 4 GB were reserved, then it'd make a huge difference. Same goes for CPU and GPU. If PS4.1 had a flagship title launch with it, the difference could be pretty apparent. Otherwise the average gamer wouldn't notice a thing. Heck people barely can tell the difference between XBONE and PS4 games.

Maybe, maybe not. The world will never know... Well, until mid-gen.

They would call the new revision with enhancements not improving the gaming experience "PS4".

If the enhancements come together with a smaller console, probably "PS4 slim".
If the enhancements come together with a bigger hard drive, probably "PS4 2TB" or "PS4 2000GB".

I would buy it if they release a ps4.1 with a 4k blu-ray player and hdmi 2.0 Any further upgrades are a nice bonus.

PS4K!

Damn I hoped PS4 would come with HDMI 2.0, much like PS3 introduced HDMI 1.3 if I'm not mistaken. That would give us 4K gaming possibility with normal framerate.

On the other hand 3D supposedly was only possible on HDMI 1.4 but they managed to do it, so no all hope lost, but not many devs would push 4K, since it would be for 2D games at best. But imagine that fuckin crispy Rayman *_*

HDMI 1.4 does support 4K at 30fps, so that can still happen. Maybe it can push a 4K Beyond 2 souls type game at 2.35:1 24fps. I assume all 4K displays will support 24p mode, so why not. 3840x1634 at 24fps is only 121% of 1920x1080 at 60fps. Optimize a bit, add some black bars and you have KZ SF quality in cinemascope 4K.

Ohh, honestly I thought it only supports 4K at 24 frames max.

This "relatively small graphical upgrade" will be completely unnoticable to the human eye. We would then be watching comparison videos of PS4 and PS4.1 run games that show they are exactly similar and not worth the upgrade whatsoever.

Well you wouldn't have any head to head comparisons to look at. It's not like a game will exist for both modes. A PS4.1 game would just have a sticker stating "Some non game features not available during play on PS4.0 systems."
