Only problem is, at least in my local meta, no one allows IA characters. Or models. Or books. For no good reason, no one wants to let perfectly good IA material into games. Even for "for fun" players don't seem to want anything to do with IA.
As for the rumors, I reserve the right to rescind any hatred for the new codex, and any assorted bitterness until the book is printed and I can order my $120 Black Templars covered 6th ed Ultramarines codex and have it in my hands. But I don't really see how anyone except jealous C:SM players are rejoicing at the loss of C:BT.
According to one rumor, no Terminator HQ squads. BT had them - Sword Brethren Termies could be added more or less as a body guard for your HQ options. No mention of Blessed Hull for the Crusader/Redeemer Land Raider options, the EC is pretty much sucky according to the rumors, and we appear to be losing Sword Brethren, I don't own the *current* Codex Smurfs, but I don't think the Sternguard have any option to buy special USRs for their squad, so Sternguard would be a bland slap in the face for our Sword Brothers. The loss of Vows is pretty big too (even if in 5th and 6th ed there weren't many of them that had any relevance, and even got further FAQed into nonsense - or completely removed...
I dunno. The trade off I guess is that we get... Mini-Thunderhawk, we apparently get the new tank (which is a pretty kit I admit) and access to the Whirlwind. We seemingly get Rhinos that we can use as taxis for any unit now instead of the one it was bought for (though in all my years of 40k, I've never, ever once put a unit back into the dedicated transport that I bought for them. Always been a one hit wonder.) and uhhhh Meganobz... errr Centurions. And well I guess we gotta wait and see what Crusader and Adamantium Will is all about, or I need to check out the 6th ed BRB.
So in closing, this is the first time GW has gotten my blood pumping in a long time (At least since 5th Ed Necrons) and... this time not in a good way. Nrrrrrrrrrr
