There's certainly no obligation to do these things, but being popular on paper gives a decent chance of them, or parts of them, being considered. Take Arboreal behaviour in Microceratus and Othnielia, a singular interactive tree is quite doable, albeit more animation work than the Lagoon platform.
Sharing profits on a Telltale design is kind of a terrible idea, so I'd say they're more likely to apply the basic premise to another small theropod, like Segisaurus, assuming they actually feel it's a popular enough thing.
It's true popularity on suggestions can become more probable to happen, it's just not a necessity for every single popular request. It usually depends on what it is overall. Real dinosaur species from said sources are realistically possible, it's just that they'll most likely not be
directly based on or be in DLCs named after where they are in those places.
Segisaurus I'd say does has a good chance.
Microceratus I do think so too, because it's an on-screen dinosaur in the flesh. For the latter, nobody knows, if it will, where and when it will arrive in the game. I've seen opinion groups say one thing or another, but I still strongly believe it is planned and set to be in something "Site B" related, only because I see that as a way they might also add stuff that's "Site B lore" and "JP trilogy lore" in nature all together in one. Like the TLW
Pteranodon design, TLW and JPIII style buildings and decorations in one set, and (just so there is a new dino species in it)
Microceratus. If JWE1's RTJP expansion pack included only two new species, what earthly reason is there they will not ever do the same for JWE2 with two, or even only
one new species?
I believe the notion that all of JWE2's expansion packs
will or
should have four new species to exist or happen is fundamentally false, mainly because of what Frontier proved for JWE1's
Return to Jurassic Park. Of course, it might be different for this game where they won't do the same thing here because nobody knows, but there's no irrefutable proof to say so (yet).
