This is going to be a big week for the Astra Militarum (Imperial Guard), as we get more and more information as to what to expect in the new codex.
This time around, we have confirmations on the weaponry of the new Wyvern, which comes 2 Twin-Linked Stormshard Cannons which are both Heavy 2's. The firepower for these seems to be building up when you can take a squadron of 3 of them. That is a lot of barrage.
Also is a hint at being able to upgrade Astra Militarum detachments.
Please remember that until we get official information, these must still be considered rumors.

Got my hands on the new White Dwarf. Flipping through it now, I can confirm the previous reports of new orders and the Cadian Armoured Fist and Wyvern. Wyvern stats are:
AV 12 10 10, Open-Topped, Heavy Support slot and can be taken in 3s. They come with 2 Stormshard Cannons which as has been previously mentioned are TL, Heavy 2, Barrage, Ignores Cover and Shred at Str 4 AP 6 48 inch range and a Heavy Bolter that can be upgraded to Heavy Flamer.
The limited edition Astra Militarum Codex is cloth-bound and will be set at 2000 copies.
One thing that I have not seen mentioned is that all Astra Militarum detachments may now be upgraded to include up to 3 Primaris Psykers, Enginseers and Ministorum Priests.
