As someone who works in the industry, I can say that there's no new IPv4.
ARIN (the organization that allocates IP address space to ISPs in North
America) ran out last year. There is no more. No organization will *ever* hand
back IPv4. It's too valuable. There's already a thriving grey market for it,
with prices getting higher and higher. 

IPv4 will never go away, but what you will see is carrier grade NAT for IPv4
from most ISPs - i.e. you will get a RFC1918 address from your ISP, unless
you pay extra for a 'real' address. 

My company will never get another block of IPv4 addresses. What we have will
have to do us. Any company that's not implementing IPv6 *today* is in
complete denial. There's no 'magic bullet' coming that will bail out IPv4.
