I think Shen has a higher chance to return than Fatalis imo. I agree that both Fatalis and Lao share a type of dynamic lore-wise but Shen has already been teased in the Jurassic Frontier. With the other Carapaceons back and now Lao, it's kinda a no-brainer for Shen to return. This is not to mention how much attention CAPCOM seems to be giving second gen, with the 2nd Gen jungle and desert returning. Shen would theoretically just be part of that effort to bring 2nd gen content to 4th gen.

With Fatalis I feel like they definitely should bring the trio back. Fatalis was after all a big part of 1st and 2nd generation games as well as Kokoto. But there is a slim chance that they don't, like MH3U that never had Fatalis but had Fatalis-like Dire Miralis and Alatreon to fill that void. It would also beg the question if they would treat Crimson and White Fatalis as subspecies (or the latter as a rare species). Considering they are trying to move away from subspecies in this game and in MHX in favor of deviants, would we instead be seeing the first and/or only Elder Dragon deviant in the form of a Fatalis deviant with only regular Fatalis returning?

All I am saying is that CAPCOM works in mysterious ways and they may miss a very obvious opportunity to bring back certain monsters.
