This is true

And why exactly do you think Sony would make games exclusive to the PS4.5? Just because Nintendo does stupid things, it sure as hell doesn't mean Sony does. And Nintendo is going to be the last company they look at when thinking about business desicions. it's called the PS4.5 for a reason and not the PS5, once the PS4.5 has exclusive games, it will be called PS5 and they have no reason to do that.

You do realize that there are such things called "third party developers", right?

For example, Hyrule Warriors Legends was developed by one of these "third party developers" I speak of, and it isn't exclusive to any 3DS model regardless, which is not a good thing in the case of this game.

You do realize Sony makes the rules right? You think Sony won't make it a requirement that they cant make exclusive games for PS4.5. Just like how they require every PS4 game to support Remote Play for Vita. Lol and you do realize there are 40 million regular PS4s right? You think Sony or third party developers are going to alienate 40 million PS4 owners? Come on, this should be common sense. I think the only reason you are thinking this way is because of Nintendo and their stupid decisions, and you really shouldn't compare them to Sony.

Basically this.  They're probably going to want to use the PS4K to push 4K movies like they did for PS3 and Blu Ray.  They may have some extra horsepower used for the OS or something.  However, these kinds of upgrades have been tried since the NES and they've never worked, so I don't see Sony trying it.

How exactly is Nintendo changing my percpetion of the situation? Didn't I just say that Hyrule Warriors Legends is playable on both regular 3DS and New 3DS? And other than that, it was developed by a third party so the quality of the standard 3DS version isn't Nintendo's fault. I'm starting to think that you're just really biased against Nintendo. =P

This got out of hand, anyway. I only mentioned the possibility of there being PS4.5 exclusives in the penultimate sentence of the OP, and the focus was more on the the possibilty that the PS4 versions of the games could end up terrible. I think you're just looking for a reason to get angry at this point.

Answer me this: Would you rather that a game safely end up as an exclusive to the more powerful hardware, or that the developers spend extra money trying to chug out a subpar version of the product for the standard PS4 users? I'd rather have no product at all than a crappy version of a game a few users are getting. Even if Sony didn't make the rule that games had to avaliable for both versions, from a business standpoint, third parties would want to release the game on both versions of the console anyway. Because money.

If sony handles it well then there won't be any problems.

No if they do that, they need to call it a PS5.

Your going to see a PS4 and a PS4.1,  that ll be more like the 3DS & N3DS situation.

exactly, Sony just needs to have a strict guideline that the regular PS4 still is the platform to optimize for unless a dev/publisher wants to make a pure PS4K game

Xenoblade didn't do well on the N3DS. Imagine how bad it would do on the 3DS.

I mean, Vita did fail for being too powerful, but the cheapness of making a powerful product in the mobile world is astonishing. Nintendo will be pulling with our legs if they keep making weak and ridiculous hardware. The NX handheld should be as powerful as the Vita/PS3. If not as strong as a PS3, then slightly less.

240p is not acceptable.
