I hope the update isn't in October because that means they'll once again skip a small holiday (April Fools RIP, Mother's and Father's Day RIP, Summer Solstice RIP) aka Labor Day and the Autumn Harvest Festival and possibly even Explorer's Day.
For the record I absolutely don't count items being available in the NookStop as them celebrating the holiday. I want dialogue and Isabelle or Tom Nook or SOMEONE to acknowledge its existence!
