My questions for any devs will there be more +1 ships eg we have the T5 connie +1 will all the C-store ships like Nebula, Excelsior have the new generation look at some point with the type 6 material etc?

I don't think the Excelsior will get a new skin, mainly because she already had a skin pack when she first came out on the C-store and it was the Enterprise-B skin if im not mistaken. The Nebula on the other hand can sure get a new skin.

I might be wrong but that's what i know so far.

The Excelsior that was released previously had the T3 for everyone which was based on the original Excelsior and the T5 was the Lakota Refit / Enterprise B + some extra nacelle choices from Deep Space Nine. The Nebula has two skins original and the one captain logan did for the T5 but he did mention hes trying to make one using the Venture saucer. I just really like the idea that the federation are taking old designs but giving them new 24th century looks. Plus the connie has 4 skins technically if you include the +1
