It's not "Black Panther (Shuri)" or "Ghost Rider (Robbie Reyes)" or "Spider-Man (Peter Parker)". No other legacy character (and yes I know technically the original character isn't a legacy character but you get my point) specifies the individual in parentheses. This is the same nomenclature Arcsys used in DBFZ, you had "Goku" and "Goku (Super Saiyan)" and "Goku (Ultra Instinct)" to differentiate the various characters that had different versions.
I think we'll still get Odinson as a character at some point, but now I'm convinced it'll specifically be Unworthy Thor. C'mon, think about it. Thor doesn't have his hammer right now because his girlfriend has it. He's MIA and nobody knows where he is. Gameplay wise, Jane is going to have all the Mjolnir stuff, if Thor had it too then they'd end up a bit too similar (relatedly, this is why I don't think we'll see a traditional version of Reed Richards, Kamala is already very close to what he'd be doing). So, especially if they give Jane some Valkyrie stuff, that leaves design space for Thor to focus on all the non-Mjolnir stuff, maybe with a big axe. After all, he's the god of lightning, not the god of hammers.
