I don't think it's so much everyone's demanding DLC right this instant. At least I'm not.
I'm just tired of them going "We've got big news for you!" and then when the announcement comes, it's something very minor. And after the people start voicing their disappointment, someone from Bethesda says "Wait! There's something else! And it's just around the corner! Stay tuned!"
They don't have to release it right now. They don't even have to release information about it. They just have to stop acting like they're going to announce something big and stand mute until they're ready to present it.
They need to keep a ruse of being active. If they just stay silent, people (who are used to Bethesda) will become impatient and use their money for something else
I for one would rather have them staying low and come with a BIG surprise when the surprise is just one week short of launch. In this regard, I have to applaud Apple. They announce products only when they're ready for production, so when the products are out, the ads are still fresh in people's minds
