Not much is known beyond the name of the mode, though it can be seen that under Shinta Mode, the number of points you get is higher. It could be that the usual points increment with hit combos no longer applies, and instead focus on your hit accuracy. Don't hit a note- 0 points, hit a note with 'good'- regular points, hit a note with 'great'- double points (thanks crystalsuicune!). Simple as that. No more multipliers. What this means is that....well, see the difference for yourself. The first screenshot is regular Taiko, the second one is Taiko with Shinta Mode applied.
The number of missed notes is greater in the one with Shinta Mode, but the score is higher? WTF. It's...somewhat appreciated, but at the same time any idiot can just bash the drum, hit random notes, and get a high score (won't matter if they don't clear the song though).
Anyway. October 1st. Mark it down, guys!
