I just checked online for you and it seems that vol. 3 is as far as they currently go. The only recommendation I can think of is to scan the back of Marvel Previews every month to see if a new one is being offered.
The new Beta Ray Bill has real chip on his shoulder. i just read the second issue of the series and he seems to have lost his nobility and can no longer lift Stormbreaker. who is the cloaked wierdo that he got the virus from?
