So let's see, we've (as of Q2) built 1 and have 4 more underway. That means that Member Worlds other than Andor and Betazed are starting 6 Renaissance ships between them.
There really is a Rennie Wave!
The build list hasn't been updated yet, so this is guess work.
The Vulcans scrapped a Soyuz to make crew available, presumably for a Rennie build - 1 or 2?
The Tellarites scrapped their only Soyuz to make crew available, for Rennies - 2?
The Humans have been stockpiling for years - 2 or 3?
Andorians want one, but cannot afford it yet.
Betazoids want one, as a defence flagship.
Indorians want one, but have to be taught Federation ship building first.
Caitians cannot afford one.
Amarkians prefers their own designs.
Rigil prefers their own designs.
Apatia prefer their own designs.
So guessing at either 1 Vulcan, 2 Tellarite and 3 Human, or 2 each.
None of them have the shipyards and resources available now to start all that immediately, but it gives an idea of their plans for the next year to two.
