It's a matter of expectations. The last two editions (and later 2E as well) had a regular churn of material. This allowed players and dms more options with minimal work. Each time the edition resets, there is a time of growth to reach what many have considered their "needs." We are in the same time of growth, but (based on the surveys) they are not going to glut the market as they have in the past. This means a MUCH slower release schedule than has been seen in more than 2 decades (possibly closer to 3). Considering that most people (especially on the forums) have never seen anything near this slow of a release schedule, it does not fit their expectations (even "slower" for many would not be as slow as WotC appears to be planning).
As a grognard, I'm used to getting new stuff when I can (not just due to the release, but availability and affordability). For me, I don't NEED anything else for 5E, but that doesn't mean that I don't WANT things. I understand the difference, however, and can wait patiently for my desires to be met.
