With WCI, Reverie and Wano all announced in a single year, Wano will probably start late 2017. Not really enough to call that his year then. That said with how Sanji's year turned out, maybe it'd actually be better if Oda doesn't define it as such. Not that it matters anyway considering that everytime he is involved in an arc, his highlight is second only to Luffy except maybe few exceptions, so doesn't really need a specifical year for him eventhough it's heavily hinted Wano will be a key moment for him
