If you do not get the title, I'm sorry for assuming everyone would have been on a PS2-4 rush with Ohayou! Taiko Summer getting on PS4-1... never mind then.
What's up here is that it was found that the classification body of the Australian government (think ESRB or CERO) has completed a classification file of a "Taiko no Tatsujin: Drum 'n' Fun!" for Nintendo Switch way back on June 15, about one week after the reveal of the English-language patch. This has to be the least Asian announcement Taiko no Tatsujin has had for the last 10+ years.
Does that mean that Taiko no Tatsujin NS1 will definitely release in Australia? Nothing is said for now, but stay tuned when we know more.
