I've actually got better hopes than that, personally, for one good reason.
Cyberpunk.
The Switch 2 version has been in dev for a lot longer than a few months, apparently, and yet the really well-running build that we've all seen in vids that was used at Switch 2 live events, was apparently a build they pulled out from waaaaaay back when they had only been working 7 weeks on it.
If the Cyberpunk devs can get something like that running that quick & good in a mere 7 weeks, then I don't think the good folks at DE will have many issues getting Warframe up & running strong on Switch 2, once they've got a dev kit.
If anything, yeah, it'll definitely be the wait for a dev kit that takes up the most time.
