As far as what to expect, here is a list that I found on another forum stating what should be fixed in an upcoming ota update (have seen a similar list on this forum, just could not find it).
“Official” DROID Bionic Bug List: Fix Coming in November, Incapable of 8-device Hotspot, 4G/3G Issues and More – Droid Life: A Droid Community Blog
Keep in mind that the priorities etc may have changed, but this will at least give you an idea. I would not panic about what you see as folks see these issues to varying degrees. You will typically find a laundry list of these things for updates to different phones when there are issues and updates. You kinda gotta filter out the rants people have on this site when they are frustrated (yours truly included ;-) but that's the beauty of a good open forum.
