Hey, why not? Wandering wish lists can partially inspire the Namco heads for the future console games! (I still hope into a Taiko Wii4 with wi-fi support for downloading new song, just as seen on PSP 2...)
Here are my wishes, rounded up by genre:
J-Pop
Ouendan-inspired songs - This can be an unusual turn of improving! I loved the 8* Kokoro Odoru.
Punishment - No further comments needed. 9mm Parabellum Bullet, give us a sign of life!
Anime
Tank! - I'm already fullfied with the new One Piece song, but an Ura release for the Anime category can make more spicier the selection.
Children/Folk
... maybe a return of the 9* Mori no Kumasan?
Variety
Yawaraka Sensha - here's a good way for asking me some apologises for the horrid Miku appearance; maybe with the squishy tanks, please!
Classic
New impossible Oni modes - why only Chopin and Mozart can play with 10*? Classic genre is always a solid part of Taiko games, after all.
Game Songs
Make Inu Henjou - already asked, but a double wave of hopes is priceless. :3
IN THE ZONE - 1/6 speed training never ends. 765 for the win!
Some Zuntata tracks about Puzzle Bobble games - I'm getting sick of only shooter-related songs...
Namco Original
Shunyuu & Zeihen - in opposition of crystalsuicune's denigratory comment about shunyuu, I insist the new song is ages better than zeihen. Both the songs are anyways invited to the party!
*2000 - Okay for Shimedore, but if there's something MORE to discover? Getting curious...
@aqua: why don't you propose something similar to our blog readers? Maybe with a poll which results will be sent to the T.Team guys with Twitter...
