#301 sound got scrapped. #309 and #320 posts have new sounds, and it doesn't really matter anymore what is being said since I decided to go full tilt with the alien language. Now you can *really* wonder what sort of creature can make those sounds!

As to answer your questions:
1. Not right now. I find Uzii's work on textures is pretty good, so that's very low on the list for the mod.
2. Of course. In fact, since I plan to have three separate releases each covering one race, the support will also continue through that. Plus, I would like The Last Stand to be decent at multiplayer as well, so that will most certainly require support and balancing.
3. Not right now. I consider moons to be "frills"... nice, but do we really need them? Plus, the scaling in the game is not really supportive of the idea. You either end up with a miniature moons which messes up the perspective of how big other things are (which is the reason I want to resize the planets) or you end up with just another type of planet...
4. Nope. Some vanilla ships will receive minor upgrades, like interdiction ability and mine laying, but aside from that I have no intention of modifying them extensively.
The goal is to have the vanilla races, when all the new races are released, feel like galactic upstarts, while also having them fully playable and balanced. That is why they are not going to get some of the more awesome units the new races will sport, such as deployable battle stations and Titans.
But it should still be interesting to play with them... with that proper "odds are stacked up against us, but we are *still* going to mop the floor with their big, bad, alien asses!" feel.
