Hype is a dangerous things when it comes to games, and it can be very dangerous for a publisher to play with their public. Take Ubisoft for example, they try hyping the Watch_Dogs games (not too much the 2nd, but still), The Crew, whatever their retarded rabbit is doing with Super Mario, etc so much, that people are not met with the expectation the publisher created, and that's how Ubisoft went on a very steep downhill by their fanbase.
Rockstar tries a different approach, they spend months, sometimes years in silence (ask any RDR fan), so whenever new information is released, it is seen as more special. However, if the companies don't fill the hole on the hype, the fanbase will, with fanfics and wishlist threads. Earlier Rockstar predictibility towards 'bigger is better' helped with the GTA IV hatebase, people were expecting a San Andreas 2.0, even larger and with more things to do, and out came a game that was smaller and more focused on story. And some people didn't like that because the game didn't meet with the expectations they've created.
I personally wouldn't mind a step back from V to master other game elements, be it the story, character development, gameplay, etc. However, I'm sure if that happens, something similar to what happened with GTA IV will happen, with people expecting more and more from the game, but in the end not getting what they wanted.
