Not a whole lot of specifics (yet?) but there are some juicy bits. From the usual place.

P26-29 is a feature on Anew, Marina, Souma and Louise:

Marina is “Preparing for Peace”
Anew is “Healing the sniper’s hands”
Souma is “A wish, unfulfilled”
Louise is “A dream exchanged for hatred”

Marie goes to sleep once again from the shock of Sergei['s death], her relationship with Allelujah reverts to an awkward one. What Souma is seeking is revenge for Sergei.

P30 is a feature on Kati and Sumeragi’s group along with Wang and Nena.

Wang has the words “You are not an Innovator” thrown at her.
The article also mentions her break with Ribbons and the beginning of contact with Regene. 
Finally, Nena will betray Wang.

[EDIT]

There’s some other stuff that’s been added to the blog post in question, I’ll get to it in a bit. Meanwhile, castlists for 18 and 19 came up on 2ch (I think these were typed up from magazine scans or something), I don’t really know what to make of it, some names are suspiciously missing (not really suspicious in the this-character-won’t-be-appearing-in-this-episode sense but more in the are-you-sure-you-didn’t-just-make-a-massive-typo sense):

Probably the most immediately apparent omission is Kamiya Hiroshi in both episodes, we know from the summaries that Tieria’s proposing his big Veda retake plan this week so he has to be in it. Also Kawasho Miyuki (Hilling) should be in 19 and Shirashi Ryoko (Anew) should definately be in 18. I guess it makes the cast lists pretty worthless/suspect, but assuming that the only issues are omissions, it looks like we’ll be getting some Bushido in the next couple weeks.

[EDIT II]
Lol, I just realized that episode 19, the one where the Anew shit is probably gonna hit the fan, is the day after Valentine’s day. ( ﾟ∀ﾟ)ｱﾊﾊ八八ﾉヽﾉヽﾉヽﾉ ＼ / ＼/ ＼
