My point is that Metroid as an IP is utilized frequently. It's not as if Nintendo hasn't used anything from it in over a decade or more.
And Metroid skipping a console isn't anything new. The Nintendo 64 went an entire generation without a Metroid title. Folks are being a bit too entitled over this whole thing, methinks.
Its an odd situation with Metroid honestly, as you are both completely right and wrong.
You are right, as the series did get a lot of attention in Nintendo releases over the years and through re-releases like you listed. And Metroid skipping a generation isn't new, as again, you bring up a good point with the N64 not getting a Metroid title.
But you are wrong in the sense that the Metroid series didn't end with a nice bang but a Sonic 06 style bomb. Other M wasn't a bad game at its core but the story elements and a few issues make it stick out BADLY among the other Metroid games. And again, the story isn't so bad its good like 06, its just insultingly horrid and takes a good game and completely ruins it for many. And Nintendo never recovered from this for Metroid, not unlike Sonic which got better over time. Granted, I'm talking about Sonic on Gaf and this place in the gaming side at least hates the series, so I'm likely wasting my time saying this but point still stands.
Metroid in my mind, ended with Prime 3 and is getting a fun spin-off with Federation Force from a studio that never made a bad Nintendo game before with me having hope for a NX Metroid being in the works in the future. But if I count Other M in this story? I would be more bitter toward the series future like many are here.
Honestly, it doesn't matter what happens with the IP; people can give Federation Force a fair chance like I plan too or can just say 'Series is dead' and play games like Axiom Verge or the fan game discussed here (AM2R).
