From Mwnciboo on Heresy 30K forums:
at the weekender they talked about a big release, rather than a trickle for prospero because tony was afraid he'd get lynched by either 1k sons or sw players, so from that came the intention for a mass release, which means they need to start now, to bank the models or else all work for 6 months while nothing gets done. E.g Concurrent activity. So while 2/3 of the studio work on book 6 and small group will be doing book 7 stuff ready to get ahead of the curve.
No mention of BA in shadow crusade by Alan Bligh, at the weekender.
From Sircyn on Heresy 30K forums:
There was talk of the ordinantus getting a crew compartment like the Krios at the back and there being multiple weapon options for it! The larger tracks at the back are Krios scale, so it's big but not mammoth sand crawler from dune big.
Also, they're hoping to trickle down the concept and quality of the titan instruction manual to newer complicated models they think would benefit from it. They don't want another model to warrant an internet survivors club!
Warlord Titan Foot - Great for scale because it's using Knight Shin Guard as like Ankle guards. 4 of them.
