I don't think the DX 01 will plummet that low on the secondary market. Maybe it won't go for 500 dollars any more, but I can't see it falling below 300 or 250.
The v1 Joker still goes for more than it's original MSRP. v1 TDK Batman and the OC still go for a pretty penny and they have been "improved".
As long as the new release doesn't have,
- grenades
- cop/honor guard head
- cop/honor guard gear
I think it'll be fine. There's also the fact that it was/is the first DX figure. I'm sure that means something to collectors.
The only problem I can see is if someone bought that sucker at 500 dollars or something. Yeah you're probably not going to get that back.
