game series that leave you hanging

[Zantetsukens-cut]

Why is it that every time a great game series ends on and epic cliffhanger the next game is canceled or the developing studio vanishes.
The first for me was legacy of kain after the mind blowing ending of Defiance they just canceled dark Chronicles in mid development. and then years later dead space the ending of DS3's DLC Awakened Isaac repairs a 200 year old ship to get back to earth just as they get in earths orbit they get attacked by another moon sized monster earth is under a necromorph Siege and cut to black roll credits. Then Visceral studios disappears no dead space 4 ever. Heart breaking
