With C1 having a single Combat group limit, I'd honestly like to see N4 limit things to 2. Allowing more is just a balancing hell, this isn't hating on spammy armies like Caledonia, but how hard it is to make the Action Economy of an elite army work in a world where you can flip Core Links in between 3 Grey AP HMGs to make their life hell. Same goes for defining table layouts that both work for a TAG Limited Insertion list and a 30 Orders CHA list, it's just impossible to have both and expect fair tables. Since Links get an overhaul according to the hot and cold on FB (link boni stay, so I guess that means Composition as well as Link size gets a look, improved Haris and Duo would be great), Caldeonia might need a bigger redesign to work in N4. Something that's not in the cards with Tohaa and every OOP Sectorial delayed till after launch. On topic: CHA is great at range thanks to inexpensive Cateran Snipers and Grey HMGs and you still get all the close range goodies on top :D
MRRF is already OoP. And there are no factions in the game with more than 3 sectorials in production. And USARF is not going out, so... @Knauf remember, MRRF and Qapu received new sculpts as part of they departure...
But the PanO ones didn't, so don't count on it. Especially with CB overscheduling releases like nobody's business these days.
Well - as someone who owns every PanO Sectorial. SAA got Dart and new Nagas from OSS. NCA got a somewhat recent Swiss and more recently Bolts, CSUs and Devas (including the excellent AHD Profile). Most sculpts for them were also up to date (3d sculpts) and they were in a pretty good place rules wise when they got benched with new Link options.
My guess is we will see a few MRRF profiles in Kosmoflot and they will get space looking resculpts. Same with CHA and the rest of CHA will go OOP. I imagine the sculpts will be similar to what they did with Koldstrom. They are still fusiliers but with cold weather gear. So maybe Biscards with space suits or whatever.
