Ollivander's Disappearance and Neville

I think it must be significant that Neville was one of Ollivander's 
last customers prior to his disappearance, but can not for the life 
of me figure out what it means.  JKR would not have included that 
information unless it was significant, after all, no additional 
information was given to us about other disappearances (Florean 
Fortescue) or deaths (Amelia Bones, Emmeline Vance).

1.  This would have been Neville's first purchase at Ollivander's, 
since he was previously using his dad's old wand, and immediately 
after he bought his own wand, the wandmaker disappeared.  

2.  Although there are other wandmakers, Ollivander is considered an 
authority; he was the one called in to weigh the wands for the 
TriWizard Tournament.  

3.  Ollivander has been in business for a long time, having sold 
Lily's wand to her way back when, and I assume that he also sold Tom 
Riddle his wand...which means that he stayed in business with no 
trouble throughout LV's first reign of terror.  

4.  LV had over a year (since his duel with Harry in the graveyard in 
GoF) to 'ask' Ollivander to create a new wand for him to duel with 
Harry; it must be something that happened recently (ie, Neville's 
purchase) that forced LV and/or DEs to take away Ollivander, or 
forced him to go into hiding.

If anyone has a theory about this, I would love to hear it.
