I feel like Crash is being overrated just a little. It's not that he's unlikely, but it feels like the main points are that "he's iconic" and "he's obvious." There hasn't been a real "hook," so to speak, that makes me think "Yeah, it's definitely him."
Personally, on the Surface, Crash does have everything going for him, in that he doesn't really have any Flaws in terms of consideration
He's a New Franchise, Sold Millions, Very relevant, Has great Nintendo Presence, Requested, Western franchises shown to get characters, and even had Lots of Japanesse popularity back in the day
Personally as someone that doesn't expect Crash, the reason I don't think he will get in is mostly because of Activision, and not even because they might be hard to work with (though that's probably something to consider), but also that being a Western Franchise, I imagine the talks will take awhile and I imagine Activision would want to be very particular, especially considering Crash makes no crossover appearances really
Crash I don't imagine was high in priority like Steve was back in 2015, and he wasn't among the most requested characters like Banjo was. So the timeframe to plan and include him would be smaller than those 2, like 2017-2018 at the earliest, and since FP2 was finalized in 2019, that's really at most 2 years to discuss everything, including everything relating to moveset like Model, Animations, type of attacks, Stuff with costumes, the stage, the Music licenses, any specific guidelines to meet and mandates to adhere to, etc
