As stated in bug #1211046 the missing U1 Sync indicator is fixed albeit it's missing an image next to the Ubuntu One on/off switch (in the indicator's menu).
Dropbox is running but there's no Dropbox indicator in the top bar.
Also, there's no U1 or Dropbox integration in Nautilus context menu, don't know if it's related.
