The SingleV is still second in the daily music dvd chart (Morning Musume is first).
The daily music dvd may not be as competitive as the singles chart, but H!P SingleV DVDs are almost the only single song PV DVDs that are released nowadays and they are selling well. Some may say Up-Front is milking the wotas/fanboys, one can also say that they are succesfully exploiting the visual nature of the idol industry.
