That's the case for anyone who (a) got their PI block from ARIN, as opposed 
to legacy space, and (b) would still qualify for that block if they were to 
apply for it today.

However, I think the number of folks that have PIv4 space (legacy or not) 
but wouldn't qualify for a new minimum-sized block is fairly small.  And, 
for that matter, most of us wouldn't miss them if they refused to move to v6 
because of it, or our users wouldn't notice that they were passing through 
some sort of proxy or NAT-PT device to get to them (if we couldn't just 
ignore them).  I'm far more worried about getting Google, eBay, MySpace, 
CNN, etc. on v6 than I am the small folks, because the small folks are 
depending on the big boys to get vendors to make their products v6 capable.
