You know what, this actually looks pretty neat. I already own a Galor (after many attempts might I add) and I got the Breen ship at Christmas. If I can score a Jem Hadar ship too then I'll have the full set.
I must say though, I was expecting to see the Warship (DS9's version) as the Lobi Ship and am surprised it isn't included in this little package. I can't help also thinking that the Dreadnought is going to be a tad overpowered. On the show it took fleets to take one of these things down. I don't envy anyone flying a Defiant Class right now.
I also hope (unlike the Chel Grett) that these Dominion ships come with their own, unique bridge sets.
