You mean like Superman?, Wonder Woman? The Flash? Green Arrow? Green Lantern? yeah, a lot of unknown characters and I am sure no one cares about them either.

Is not about flopping, is about costs... Porting Origins and City was cheap, not a lot of effort required, porting this new one should be expensive because there is no 360 or PS3 version, so most of the assets have to be redone, textures reworked, and so on. Porting this game is not cost efficient, so even if the previous games made some money (which is possible taking into account that are ports that sold over 150k units), this is a higher risk, besides Rocksteady does not have ANY experience with the console.

There was absolutely to gameplay in that trailer whatsoever. When is CGI finally shelved? There is no pont for it anymore.

In game cutscenes look good enough in this gen to get rid of cgi all together.

The trailer got me excited for it. I will likely pick it up for PS4 during a holiday sale.

I havent been excited for a CGI trailer since the PS2 days. I would think with all this focus on ingame graphics that any attempt to use CGI in place of it would be frowned upon. CGI literally does nothing for a modern game. I honestly cannot think of one thing. 

What's so fun about playing as Superman? 

"Oh look at me, I'm invincible and can fly at the speed of light and any movie/comic/game involved armound me is boring unless someone has kryptonite, but we all know I'll beat them up anyway". 

Batman movies, series and games are interesting because he isn't overpowered. Yeah, we know he'll win, but we never know HOW. Superman just beats everyone up. 

Rocksteady should make a Tintin game, that be so exciting. He's a much better comic book character than all your examples anyway. 

Although I've been a fan of Batman, he's been overdone to be honest, it doesn't help when writers start making him smarter than everyone else.

I love The Flash, Green Lantern etc, because they have strong mythology. Sadly Warner Brothers doesn't care about the mythology, because the executives are about money than quality, that they rush something together, that they have their own hands in (like that recent GL movie).

I'm just getting bored of Batman at this point.

The Flash would be pretty hard to make a good game out of, but I guess it's possible(as long as it isn't made by the Sonic team lol). Don't know the Green Lantern to be honest. Well, I do know him by name(big bang theory and all), but that's about it. What's his power? 

I've only just got into Batman, so for me it isn't overdone yet :p

I really just hate characters that are overpowered/ridiculous.

They made a GL game, but it was a movie tie-in (rushed, glitchy, repetitive) so it sucked.

He has a ring of infinte green power (does anything he wants), and I do think there is infinite possibilities for the concept. Games like Gods Among Us, I think show that a GL game can work (that game also showed that a lot of DC characters can work for their own game).
