They are doing what they can and want afford just enough to give her 'ok/good' sales...
The promotion surely is better than having many different versions of the album, there should be many leftovers from NEXT LEVEL by now... many that people did not buy, so having just 2 versions is much better.
Is all about the tour I guess... as long as people keep feeling interested in going to see her
P<F is so overrated xD I love namie and all that, but if that album is topping the Japanese charts means that Japanese music in general is pretty meh nowadays, so meh that is not worth buying.
Seriously, Japanese music had much better times a few years ago, to me everything before 2007 was good/fresh, but since then everything seems repetitive, plain, boring, etc.
EDIT: Maybe the K-pop boom was all thanks to the downhill of J-pop, not that K-pop is good, but J-pop just got worse.
I really admire namie, and I'm really proud of her, as well as I'm proud of ayu that keeps on working really hard.
(I should kick myself and listen to Don't look back now

)
Anyway I'm not sad or anything, I'm really happy for ayu
