Do they have a warlord trait list and a wargear list?
Any unusual items?
Sorry Tangi. Can't help you there.
I did, however, read over the new tau rules.
Tetra: I think the precision-markerlight-thing's mechanic of being TL nicely evens out the fact that the tetra doesn't have access to the targeting array anymore. Pretty good buy for its points, and definitely superior to the Codex: Tau Empire markerlight suppliers.
Barracuda: meh. I'm still not particularly convinced. Maybe it's because I use flyers as AA units, and in Tau, there's better things to do that then the Barracuda. This is a personal opinion, of course.
Manta: God, the rules for this thing get stranger each edition... 90-ish burst-cannon shots... GW isn't being conservative with big numbers it seems.
I don't play Apoc, however, so I can't make a factual opinion about how good this thing is. This applies to all the Apoc units.
Heavy Gun Drones: As with their previous rules. Just not worth it for the points.
Drone-Tower-things: Good, perhaps, for a static, gun-line list where someone might get some use out of these things. I will not.
