So, I got the Core RT book and I was thinking about getting some splatbooks for it this holiday season as well.... however, the main book I hoped to get, Battlefleet Koronus, has been out of print since before I got the corebook a year ago.
Do you think they will reprint it soon-ish? Or will they just ignore doing any RT prints until they give it a new edition like Dark Heresy?

I remember waiting for the Dice for WFRP 3e, which in the end, was a pretty bad experience...

I would expect no. If they do anything for this, it'll be a new book, for some RT 2.0; the old books for this line have come and gone, I think, and Ebay, Amazon, or something similar might be your only hope. I can't say they've abandoned RT, up at FFG, but I wouldn't expect it, in this case. Sorry.

I believe it's still available on drive thru RPG if that helps.

Awww.... that's really disappointing to hear.
From the looks of it, BFK is almost as important as the Core book and there is high demand and low supply.

I guess I'll still hold hope though..... Only War and Black Crusade still need a lot of splatbooks and some WFRP stuff got reprinted.... including some at rather questionable times.
(Come to think of it, the most useful splatbook for OW is still out of stock too, despite being from a new-ish line)
