When it comes to a new codex, you are always worried about what is going to cost more, and what is going to be taken away. This Astra Militarum has some big changes coming, and included in these changes are point cost increases to the Chimera APC, Vendetta, and the removal of some favorte Artillery pieces. Most of this is getting confirmed now with picture leaks.
Lets take a look first of all at where you can go to see some of these leaks.

Please take the following as rumors, and these are things that I have been reading over the web, and the leaked list builder image was on 4chan earlier today, but is gone now.
Now there are some leaks that are still coming out on, that show a page from the list builder in the back of the enhanced version of the codex.
The Chimera will get a lot of the upgrades (the new ones) that we saw in the Tempestus codex, quite a few of them for cheaper points. The first thing though to note is that the Chimera is going up in points. The base cost for a chimera is 65pts. You also will be paying for your search lights now an additional 1pt.
The Vendetta is confirmed at a 6 person transport capability, and is sitting 170pts.
Platoon Heavy Weapon teams can take a Missile Launcher with krak and frag for 15pts, and add flakk missiles for an additional 10pts.
It seems confirmed now that the Griffon, Colossus, and Medusa are not in the codex. They will still be playable, but you will need to get IA1 to do so. Also a chance on where you are playing that forgeworld models will not be allowed.
As a heavy player of Chimeras, I own 10 of them, I am a little bummed out if the cost is this much higher. Now it will make up for it, if there are new weapon options... like possibly an autocannon, but I wont be crossing my fingers on this one.
