Forum:Does Bethesda announce fixes?

I was wondering if there was a way to know which problems Bethesda is aware of and be informed when they put out a new patch. Specifically, I wanted to know if they plan on doing anything to fix ED-E's many circumstances where he simply disappears. Yes, I have used the vault 22 trick. When it didn't work the first time, I went back to the 38 and visited Mr. House to try setting him to "wait" (in case he was simply stuck somewhere) and then went back and used the elevator again. No good. I am playing with the 360 and I want the "all companions" achievement, so if someone know where I can look at this information, or has any helpful advice for my current problem, that would be great, thanks.
