We didn't post about this Judge Connolly opinion when it came out back in October, but on revisiting it, I thought it was worth noting.
In deciding a transfer motion, Judge Connolly suggested in a footnote that, for Delaware LLCs, venue may not be proper in Delaware unless the individual members of the LLC are citizens of Delaware (which often may not be the case):
