These are both pretty much my thoughts on the matter. Verge may have been right (mostly, barring the Minecraft content claims and Echo Isabelle) for the base game but when it came to DLC they blew it, being adamant about one of either Erdrick, Sora (shot down by the French PR statement), Sephiroth (unlikely due to FF7 still having only 2 tracks; UNLESS he were individual like

), Geno, Crono, or Slime at the VGAs. And well, that didn’t happen thanks to this guy:
As for Star Fox Grand Prix, that was PROBABLY just the Switch exclusive Star Fox content in the Switch version of Starlink.
or it could ACTUALLY be a new F-Zero at long last let me dream
So yeah, I’m probably not believing any leaker for DLC unless it can be verifiably backed up a la ESRB/Roy and Ryu/Ken.
