They HAVE been up at least since Thursday last week, they are not TRUE Soverign Bridges, but they are a take on the "Diplomat" bridges (Diplomat, Star Explorer, Ceremonial, Alliance).
San Francisco has a nice color combo, has same colors as thr Galaxy refit bridge.
Eaves is a nice looking "red alert" kinda bridge, dark and red, I like it
Zimmerman, while kinda bright for my tastes, does have first officer and counselor chairs.
WOW! No one uses the search function around here. Yes, they have been in the C-Store for about a week. The 3 in the pack do not look like the Soverign bridge from the TNG movies but are decent and well worth the 96CP.
