As you should all know by now, we live for 30k and the whole Horus Heresy timeline. We look for patterns and trends which Forge World may be keeping to.
At the Horus Heresy weekender 2014 Mortarion was released (17th of July), the Wednesday before they showcased what would be at the event so you could start budgeting your spending :)
Now with another event imminent, and it being the Wednesday before tomorrow, I think excitement should be building.
So I believe we may see a sneak peak at the next Primarch tomorrow.
Egan Sculpted Roboute last, and we know Edgar has been sculpting one. The event on Sunday if following previous formats will not have seminars. If that is the case then could we see a WIP Primarch in a cabinet if not finished, I don't believe so as we have never seen a Primarch like that before.
I don't think it will be Dorn as the Imperial Fist gamers have been well and truly sated recently with the other 2 characters.
There is a chance it is Corax. Hayes has been looking into how they can make his jump pack work. I believe this will be done by Egan though as it is one of his favourite characters.
Alpharius is the other possibility, but Armillus was released not too long ago and so I think they have been looked after recently too.
So I believe we may see Perturabo tomorrow. 3D sculpted by Edgar and looking fantastic.
Other than that, possibly a Sokar, White Scar mk2 upgrade pack, The new Ultramarine squad, the Bloodslaves and their master, Ventanus and Transfers for the Iron Warriors, Alpha Legion and Night Lords too :)
Hopefully some more merchandise too including a Mug with a Titan "T" on it and maybe a Night Lord T-shirt.
Obviously Wishful thinking, but let's see if a pattern is followed.
