>>1122189630k guilliman would get a cape and scabbard more, but lose the mounted bolter, downgrade his sword, and not have an included/official helmeted head. Power fist could be articulated, or it could swap between open and closed like the 40k version. He also has a holtered pistol on his back waist, and considering they've given every primarch every weapon depicted on them, then he'd have a pistol over his 40k version. Seems kinda similar, all things considered (downgrades sword, loses helmet, gains cape, swaps mounted gun for holstered pistol), he'd have to have articulated fingers in the power fist in order to put him on the radar, in my opinion (but to be fair, I like his 40k look much more than his 30k).
30k lion gets an extra dagger, and his pistol would now be functional, AND has an official helmet, so he wouldn't be lacking there! Though, compared to his 40k counterpart, he'll come out lacking (loses 2 alt heads [hooded helm and hooded unhelmed], swaps mace [carried by little guy] for knife, loses shield, scabbard, and two little guys, gains pistol). Presumably.
Again, though, I find his 40k appearance superior, as it is much more distinct, rather than 'slightly more ornamental power armor, with robes'.
My guess is that they'll do them two last, to give them appropriate space between their 40k versions (I don't think daemon/40k versions of primarchs would need this much space, as they are a lot more distinct than a change of armor).
