Those are new games, sure. But maybe we'd see more if they weren't doing so many recycles of games we already played.

we wouldnt. see, the problem with your reasoning is that you say "imagine the number of hours, money and resources wasted on these games". 

1- you are lumping all these hours together and imagining how many new games could have been made. reality is this.  you cant just lump the hours, money and resources together, it doesnt make sense. they are all by different devs, who put a small number of people to work on these ports, remasters or what ever you want to call them. as it was pointed out, the dev still works on their main game. if crystal dynamics and naughty dog didnt make TLoU:R and TR: DE, the people who worked on both versions wouldnt come together and work on an entierly new game, that doesnt make sense, they would work on UC4 and RoTR, and while they would help with the development of those games, they would lose benefits i will explain in my next two points

2- you are treating games solely as a form of creative expression and art, when in reality they are not just that. these are business whether you like it or not. and before you slam the publishers for being "greedy", remember who pays the bills and that the devs want to put food on the table, pay rent and put their kids through school. these remakes make money, give gamers who havent played the chance to play them again, and give the fans of the dev/franchise/game a chance to replay it if they want with improved performance, and ultimatly, dont really effect the development of the real game.

3- devs gain experience, money and knowledge from these remakes. porting these games to new hardware helps the devs learn and experience the hardware. they dont have to create the entire assests from scratch to try releasing a game on the hardware, they already have the game, now they just need to make it work, and its fast and helps them a lot with their new game. so even if a small group of devs arent working on the new game, their work on the port helps the development of the new game by: 

A) they learn, build and gain the knowledge to make rendering tools and know how to ship a game on the hardware. they know how to encounter some problems they might find with shipping the new game, saving time and resources. 

B) they gain profits to help invest on thier new game.

you are acting like these man hours spent on these ports mean nothing, when reality is they have great benifits for the publisher, the dev and the new games in development. while also giving gamers something else to play, its not like there is a lack of games releasing now or releasing in the future. Q1 is literally packed with games and we still might get more release dates for some smaller yet interesting games like rime or the tomorrow children. 

Would be nice to have a DS2/Bloodborn bundle.

"Companies exist to make money" sure, but it doesn't excuse them doing it in shitty way. Even if the manpower was merely shifted to existing projects, then those projects would be done faster and better. Instead we get offered reheated leftovers. That's simply not good enough in my book.

Most of the ports are actually outsourced so really there is little to no shifting of manpower for many of these ports. And otherwise as already said bringing an existing game over can actually help speed up development as you can ensure smoother development of new titles.

For example

"This was a little bit like Christmas, in the sense that you get to spend five months exclusively working on engineering problems," says Gyrling. "That was wonderful, but from a business standpoint it just makes so much sense to tackle all the difficulties of shipping on a new platform with an already made game." Shekar readily agrees: "Shipping this game means that Uncharted 4 will not be our first PS4 game. The first game on a new platform is very difficult to do, and now we've already done that."

Not a fan of the series, it's too hardcore for me, I hate dying in video games.
But it is awesome that one of the best games in 2014 will finally be available to people owning next-gen consoles. It is always great to have more choices...
I am so happy that PS4 and XOne users will have a choice to buy this game. I will not buy it, but I hope many people do, and that the series gets as many new fans as possible.

Also, I expect this game to score even higher than the original, since it is adding new content on top of that already excellent game.

Bloodborne + Dark Souls 2 bundure for $439. Do it Sony!

But even outsourcing studios are very often brought in to assist with production of massive titles, we've seen this with games like COD. The industry as a whole has a finite amount of manpower and resources. I'd just rather they focussed on actual new experiences.

Guess we'll just have to agree to disagree.

There is no shortage of developers looking for work what with all the mass layoffs and studio closures. There are dozens of studios looking for contract work. CoD doesn't use much outsourcing actually, they just use multiple internal studios. Would you rather that studios layed off people because they don't have the extra work? Seems like that would be a net loss for the industry.

I doubt the work will ever dry up, with each gen games take more and more manpower. If anything, we seem short on manpower.
