me too, I doubt we'll see a p[rimarisified Logan Grimnar, his plastic mini is too new, but a primaris dante and azrael would be spiffy.
Eventually all of the Special characters will be Primaris-ified, or killed and replaced with new characters to fill the old role. A 10 man Intercessor and a 10 man Tactical squad are roughly equivalent on points - other 1.0 and Primaris units are similar - and not quite as equivalent on value but close enough. If your special character you're running the squad with is Primaris, you run the Primaris unit and a Repulsor. If the SC
is 1.0 you run it with the 1.0 squad and a Rhino or a Land Raider variant. They're not going to cancel 1.0 Marines, they're going to let us do it, and they're going to make it EASY for us to do it. That's why the newly minted Reserve Company Marine driving a Repulsor has the clout to tell Azrael to get his butt out of a Primaris Repulsor and why Primaris Marneus can't fit in a Land Raider.
Marneus was easy. We already have Aggressors with auto bolt storm two fisted death, he was already a Terminator with two fisted death - and a - I forget where they stashed the 4++ was it the Laurels? - so scale, invuln, weaponry and size rules were already pretty well taken care of. Azrael and Dante are being held up by their wargear. There isn't a melee jump pack unit to inspire/starting point a new Dante sculpt, plus the Melta Pistol, plus the axe (SW
have a lot of power axes, Blood Angels not so much). Primaris aren't using combi-weapons which is tough for Azrael, Logan is probably held up over debate on what to do with his dogsled. Enough Space Wolves have power axes already that Morkai isn't an issue. Ragnar will Primaris-ify fast. Dude on foot with a generic bolt pistol and special chainsword? Easy peasy.
