Looks like we get both a T3 and a T5 ship. In addition, from the dev blog it looks like the T3 version is a permanent mission - it only says the T5 version is anniversary-only.
Too bad the klink ship is a new design. I was really looking forward to getting a giant BoP.
EDIT: Were we all stalking the STO website waiting for the dev blog?
Yep, I'd like to have the BoP also.
If you like models, I saw this post by T'Bonz
