I just saw that there was a video in the preview and watched it, now some comments on that:
are the explosions different? at ~ 1:26 I saw something that looked more volumetric than the usual things and also more pieces flying away from explosions.
these orgev torpedos do seem a little loud at times and overshadowing other sounds. but maybe it was just the proximity.
just a little other comment. in that build the music was obviously disabled and it was probably a isolated demo battle, so no event cards like "production finished" "research finished" showed. but it still showed that the scenes just lacked the sort of atmosphere that battle chatter and dialogue add. a few messages thrown in would rock, best even if they rougly represented the battle situation (which a rough analysis of ships in the area should make feasible). homeworld was such a nice example. you remember "command, this is a cakewalk" or "we need reinforcements here!" and more. audio is a much a source of atmosphere as video.
