That drop seems alright for Freedom Wars considering there were some concerns about people complaining about the difficulty. These are the 2nd weeks of all the Vita games which broke 100k in the first weeks (if that makes sense). For a hunting game, and for Vita games, 72% is fairly respectable, I was worried we might see something more God Eater style (>80%). Basically matched Soul Sac, but at a higher level
Final Fantasy X / X-2 HD Remaster* - 50,368 / 224,943 (72.0%)

Freedom Wars – 43,160 / 232,048 (-77.2%)
God Eater 2 – 38,534 / 303,365 (-85.4%)
Soul Sacrifice – 31,406 / 143,368 (-71.9%)
Sword Art Online: Hollow Fragment – 30,629 / 173,865 (-78.6%)
Persona 4: The Golden – 24,877 / 162,005 (-81.9%)
Hatsune Miku: Project Diva f – 17,851 / 177,539 (-88.8%)
3rd Super Robot Wars Jigoku-Hen – 17,806 / 144,747 (-86.0%)
Hatsune Miku: Project Diva f 2nd – 15,784 / 115,969 (-84.2%)
*FFX had stock issues and it was selling over the new year which seemed to sustain its sales for longer than would otherwise have been the case, so FW probably would have been 2nd in this list all else being equal, plus it's still tracking ahead against where FFX was after 2 weeks
Not a lot of good news besides that, though I guess the longer Vita stays above 15k the better
