I'm not bothered, really. Sometimes they just can't talk about things, especially this far out from release. Who knows how much may change between now and then; maybe they don't even know.
I trust Bethesda, it may all be PR sure, but the way they talk about how much they just like making games makes me feel all warm and fuzzy inside.
Basically, what I'm saying is, devs not present on the forums are busy working on developing the game and that is A-Ok by me
