These are all wip and no release timing is available. Codex SM is not underway, so these may be a splash release or could be a long way off.
New tactical squad. Hvy flamer. Mk 8 style
Edit: there are more mk 8 bits here than before, but there are still "beakies" too. Includes many options not released before in plastic, including a Hvy flamer, a backpack style (read devastator) missile launcher w flakk missile, slings on bolters, power weapon options. Basically think of all the blinged out options you get w a BA, SW, GK box and now apply it to tactical marines. Poses are all standing, but they aren't as static.
New assault squad. New jump packs. New weapon options
Edit: retooling similar to tac squad. The jump packs are all new, but don't get knickers in a twist cause they are the same style as current ones. They just look better cause the seam is not there. New cc options in the sprue include thss and lc. There is a few new options in here I can't reveal.
New librarian mini sprue. Codex options included
Edit: this is where the librarian/chaplain kit I saw a long time ago went. Has a force sword or staff, has combi weapons, has pistols. Two heads. All in mini sprue. It's 2 mini sprues. Only options from current codex not present are jump pack, bike, or TA. No info on where chaplain went.
New Techmarine mini sprue. Conversion Beamer.
Edit: very similar to current tech ax Techmarine. Layered body. Has tech ax, tech sword, plasma pistol, combi weapons, couple variants on servo arms, and conversion Beamer. 2 mini sprues.
Edit: on both these mini sprue characters the heads and weapons are compatible with existing line. But the arms/bodies are unique.
New scout box. New sculpts. Combined boxes. New options.
Edit: includes some new scout only weapons. Heads are less bulky. All codex options present in one box.
New flyer. Interceptor/bomber. Flat but boxy. Storm raven sized. No transport. No hover. Heavy assault cannon and ff missiles. Or bombs and servo drones in gun pods.
Edit: shares wing/engine aesthetics of storm raven, but fuselage is flatter. Wings not as bent. No thrusters in wingtips. Two tail options, one for each build.
New scout transport. Like Tauros (FW ig) but open wagon style. Halo warthog mashed w rhino. Pintle TL HB.
Edit: rumored rule only will allow pintle weapon when unit is embarked. Fast vehicle. 4 buggy style wheels. Rider models/bits compatible with new scout box. Roughly rhino sized. For Baja race fans think armored sandrail.
