There's not even a sniff of what models might be brought out in wave 3, and we're already all very excited. There's heated debate around whether we'll see Gozantis, Lambdas, MC40As etc. (see here if that's what you're interested in).
Beyond specific ships, however, I'd be interested to know what types of ship people are hoping to see, for either Rebel or Imperial fleets. What roles do you think are missing in your build, and how would you like to see those holes filled? What aspect of your game could be improved by a dedicated design, rather than adapting a pre-existing one?
I, for instance, would like to see a dedicated carrier. At the moment I use a Victory-I with a variety of upgrades, but it's an expensive way to build something that I'm mainly using to defend against fighters. A cheaper ship with fewer guns but high squadron activations would be ideal.
