I think next edition is going to be full of minis because:
A) old minis have to go back to fantasy to not share space. (Seraphon/sbg/cos final refresh, ogors refresh, maybe ugly demons replacement coming from a release in 40k)
B) non plastic minis are going to get a refresh or disappear
C) first edition armies will follow the ironjawz path. (Idk, fs, dok (maybe with malerion)
D) New armies (chorfs, at least, maybe malerion, maybe silent people)
