1. Fox alt isn't Wolf. Just a grey Fox.
2. If Wolf was cut, why wouldn't they at least make the Fox alt look just like Wolf, especially with the koopalings and Alph being a thing?
3. The screenshot isn't the game's final build.
4. Mario/Pit are proof that having a palette swap resemble a character doesn't equate to a loss of the character's playable chances.
5. Dark Pit no longer being a Pit costume makes sense since Dark Pit is literally just a black Pit. They would be indistinguishable. Same with other characters like Blood Falcon and Dark Link. Wolf does not have this problem.
6. If anything, this alt may be HINTING to Wolf's presence as a hidden character. It could simply be a teaser.
7. As others have said, Wolf could very well get a "Fox" palette swap as well. They're rivals. Referencing each other, like Mario and Wario's alts that resemble one another, makes sense.
8. Fox needed a couple of new costumes to fulfill the 8-per-character feature. Add a grey wolf-like one. One more costume to go.
9. Falco in, but Wolf out? Dark Pit and Doc in, but no Wolf? PLEASE.
10. Unique movesets that aren't especially resource intensive (like Shulk, Rosalina etc.) should never be cut anyway unless there's a licensing problems (Snake), an abolished feature (PT) or is an extra from a dead, relatively unknown/unplayed and overshadowered series (Lucas). Wolf is safe from all of these.
11. I like Falco and mained him in Melee. But having just him and Fox seems...wrong. They need some antithesis.
12. 4 days remain. Hope lives on.
13. 5 slots (potentially) remain. HOPE LIVES ON.
14. "PLAYTIME'S OVER STARFOX. I CAN'T LET YOU WEAR THAT! CHALLENGER APPROACHING!"
15. ???????
16. WOLF PROFIT
