About the 11/12 Asia thing, it's actually pretty good here. There's 3 places that I know where there are these machines, along with some Japanese versions.
But god dammit, no 13 in Guangzhou.
11 Asia is obviously inferior to 11, due to its lack of Folk/Variety. Same with 12 Asia, but it has Naked Glow, Obsession Latino, and Angel Dream (Ura), something that 12 doesn't have. But 12+ has these included along with many other new songs, not to mention Wii2 included Obsession Latino, so 12 Asia is once again deemed obsolete.
(Psst... fun fact with Stage.0 ac11 in 11 Asia. It is missing 2 notes from the original version, and both are right before balloon notes! Proves how unreliable the Asia mappers are.

)
I really wish there is an "Asian song" special, which will include ALL the Chinese folk/pop songs included in 11 and 12. Of course, there will be a few Namco Originals and Game Musics here, just like PS2's Anime Special.
And Taiko 14 better include OL, the new download song from PSP2, along with the Asia-exclusive anime songs.
Hopefully a sequel to Mint Tears too. Also, where's the 3rd and 4th songs of the "PaPaPa Love" series? (Unless Metal Police is 3rd.)
