I truly hope you're right, because bethesdas lack of community communication has made me lose alot of faith.
About the time issue; go see how often and how fast CCP releases patches, and you'll see why i might have doubts.
(Yes, I know. Two entirely different games, but still, if they manage to release quick fixes over night, and extensive patches after a weeks time, so should bethesda)
The time between releases depends on the processes used by the development team. Most of the larger, more-established teams have a fairly set process, and it takes time to work through all of the steps. Other development teams might use more responsive development processes, or may have next to no fixed processes for updates.
It also makes a difference if the patches then have to be sent out via a third party (e.g. Steam, XBox Live, PlayStation Network) or whether you're in control of patch distribution (e.g. MMOs). If you control the distribution then it's far easier to re-release an update if a bug is introduced - you can get the update out whenever you like. If you need to go through a third party then you've got to wait for them to do whatever it is they do (e.g. XBL or PSN testing).
With regards to Bethesda communicating with the community, I don't expect too much to be said. It's a matter of managing expectations. If you say that something might happen, and it doesn't, you can guarantee that a bunch of people will get angry. It's easier to not say anything until you're 100% sure that what you're saying is true. You can't just have the developers coming here and posting in an official capacity either, as people tend to abuse that communication channel. I've seen it before on other game developer forums, and it's not pretty.
