You're right, but this waiting without any hint is nothing short of annoying.2016 dates were announced in late september for May - 8 months.
2020 dates were announced in mid november for May - 6 months.
2024 dates were announced in mid october for September - 11 months.
So, 2024 aside, every other time in the last decade they announced Oceania dates 6 to 8 months earlier.
Can we stop saying something is off just because the management is doing what's been doing for more than 10 years?
