Since FEEL sold very close to 400,000 according to Oricon's numbers, it's very possible that Avex's internal numbers for the album are over 400k. Remember Oricon's numbers are actually estimations based on a formula and not the real number of copies sold. Sometimes it's sold more, sometimes less. This is why Soundscan numbers are different too, because Soundscan is based only on POS information from stores directly. Oricon also doesn't count everything, like the total number of CDs sold from concerts and events. Anyway, I'm not aware of Avex releasing internal numbers for FEEL, so that information on wiki is probably not legitimate.
_genic sold/is selling what I expect it to. My earlier predication said it would sell close to 250,000 total. In the long run, I think it will sell between 225k to 240k depending on its longevity. I know people think these numbers are bad/poor, but realistically speaking the album has no hits and no tie-ins. This is an album being sold based solely on her name, so I think the result is still pretty good. The album with hits or not, was probably never going to outsell FEEL. Even if it had a hit, I don't think it would have sold too much more than 300k not with the continuing dwindling of sales in the market.
