Dont expect so, even if TLOU2 slips from 2019 into 2020 it will still arive before PS5 launches at the end of 2020. TLOU PS3 also came out in the same year PS4 did.

Questioning whether PS5 will have a disc drive is just ridiculous. Sony has a big market outside developed Western nations, where data caps and speed are not the best, hell they still suck in most places in the West. Games will go upwards 100-200GB in the next gen, exceeding data caps of an entire month for a lot of people,  the bluray discs to contain so much data already exist.

And dont expect 60fps to ever be the standard, it hasnt been since the 90s on any console. Available power will always be used towards making a game prettier.

It took Naughty Dog from June 2013 to May 2016 to release Uncharted 4. The problem is that Uncharted 4 LL is way bigger than left behind. I clocked 10 hours with most treasures and the side treasure hunt completed. I also think TLOU is going to be ND is biggest game to date. With a few big open world parts (Uncharted lost legacy Western gates big) and more surviving than present in TLOU. Which was very linear.

Doubtful. Lost Legacy was made by an entirely different team, meaning TLoU Part II has been in production since Uncharted 4 launched. So it'll be out in 2019, or possibly even late next year. Also keep in mind that TLoU is a sequel so a lot of the groundwork has already been laid out.

Given how important Naughty Dog has become to Sony, its very likely that they have two teams that are big enough to handle two big projects at once.

I do think that maybe it will get the first game treatment.But I still thats very likely that the game will just release for the PS4 for now and maybe get the Nathan Drake collection treatment(in the sense that it will be ported 2 or 3 years down the PS5 lifecycle).

A couple points you're missing though, the first game on a new console is almost always expected to take longer. On top of that Uncharted 4 had issues during development which led to a change in the leadership and the Sotry, characters, actors, etc. were changed. Basically Uncharted 4 development cycle is in no way indicative of ND's normal output, which since they started Uncharted series has been a new game every two years if not sooner. Let's say Lost Legacy was a game that actually stopped them from actually starting work on TLOU2, I think we can still expect TLOU2 in 2019 at the latest.

What if the PS4 version is 1080p/30 the pro is 1440p/30 but the ps4 is 4k/60 ?

Uncharted 4's reveal trailer was shown at e3 on june 9, 2014. The game released two years later on may 10, 2016...

I would buy the ps5 regardless of when it releases and what specs it has so it doesn't really matter to me, but I see the ps5 arriving in 2019 and I would just play the ps4 games on it, I never got the pro cuz I was going for the one X but the ps5 will have exclusives I cannot play on my launch ps4 so the faster the better :P

Well you make some solid points about the Uncharted release schedule and the misfortune that did go along with making the fourth entry. Effectively delaying the game for 6 months probably, the first TLOU title took way longer to develop than an uncharted game, almost double the time even. I also believe this title will be very ambitious in size and scale, since that is what Sony is currently doing with most exclusives.

For example Horizon Zero Dawn is probably the biggest game ever produced by a western PS developer, Uncharted 4 is the biggest Uncharted game  and I wouldnt be surprised if the new god of war i's also the biggest in the seried. Not to mention Detroit or Dreams.

So I don't think Naughty Dog with all its recent layoffs is able to produce their flagship PS4 title in less than 1 year with a half team and 3 years with the full team. I can fully see them taking their time on this one, since they also don't really need to release TLOU in a brief period of time.

According to Michael Knowland's LinkedIn profile and hints from Evan Wells TLOU 2 has been in development since 2014.

From the article:

The Last of Us achieved massive success both critical and commercial, Sony shipped over a whopping 7 Million units on PS3 alone. So, it was expected that Naughty Dog would come up with a sequel at some point, and if LinkedIn Profile of Michael Knowland is to be believed, fans of the game might not have to wait long for a second chapter. According to his LinkedIn Profile, Michael Knowland finished work on “The Last of Us 2 - 1 month prototyping head sculpts” at Naughty Dog in April 2014.

Additionally, Naughty Dog Boss Evan Wells admitted later in 2014 that the second team at Naughty Dog was developing something on the scale of Uncharted. "We definitely have another project on the scale of Uncharted in very early pre-production stages," Evan Wells said back in June 2014. "We have the sizeable team that it takes to get something like that off of the ground, but it's got a long runway in front of it. We have a lot of great ideas, and some stuff that is already getting everybody jazzed and excited."
