Splatoon 3 is definitely aiming for a May-July release. Nintendo's marketing team always positions Splatoon as a summer-y game.
My big question is where does the
next Xenoblade slot in? Assuming
those reports are accurate, does it land in the first half or second half of 2022?
This is just pure 100% speculation
(not based on any insider info), but can you imagine if Nintendo did something like...
Bayonetta 3 in October
BOTW2 in November
Xenoblade in December
Having those three games back-to-back would be pretty insane.
(For context: Xenoblade Chronicles X and
Xenoblade Chronicles 2 both released in December. While
Xenoblade Chronicles: Definitive Edition was a May release.
