I know for a fact that GW have been working on new sisters of battle mini's but whether they will release any new boxes is another issue.

I am hoping that they are going the same way as the blood angels did. White dwarf Codex release which everyone bitc complained about and then a brand spanking new army released at a later date. Fingers crossed the sisters get the same.

In other news, I purchased my 20 tactical marines today. Lucky me, I have enough spare parts in my bits box to make a captain, 4 honour guard with flamers, 3 sanguinary priests (one going into the honour guard), 2 sergeants with power weapons and the rest tactical marines. Woot.
