Minecraft Story Mode was not a disappointment for me... Because I was expecting it to be bad from the beginning.

Telltale has lost their magic since The Walking Dead Season 2.

Apotheon and Infamous: First Light ?

I played through Infamous Second Son so i felt no need to play First Light but both off those are cheaper digital only games. I mean PS3 still get's a lot of (older) retail games, why can't they do the same for PS4?

PS4 is barely two years old, and I think many publishers don't want to give their games for free at this point. PS3 on the other hand can throw pretty much anything from the past 9 years especially now since PS3 software sales are declining.

I was disappointed (already three times this year!) by Camelot Unchained, first they delayed beginning of their alpha tests to March, then 5 months later they pushed beta from August to October, and recently pushed it to "somewhere" in Q1 2016.

PS Maybe "disappointment" is strong word, and I understand that stuff happens and so on...anyway, I'm not a happy puppy about it :P

PS3 already got retail games from the last two years for free, like Thief. So why not the PS4 version aswell?

Like I said PS3 is an old console with declining software sales, it doesn't really matter if the games are five or two years old, they won't sell as much in general. Compare that to PS4 with increasing install base, even niche games like WWE 2K15 can reach 1 million, it would be foolish to throw away too many AAA games too early, and remember that Sony alone can't make the decisions here.

It wouldn't be a business model if they'd just throw AAA every month, it would be charity. They did give Driveclub and Injustice: Gods Among Us this year and that should be enough.
