I don't know about timeframe, but I certainly don't see it soon.

I'm not sure that is widely agreed on.  Specifically, I am not sure
there are many features of v6 that are wanted and haven't been ported
back to v4.

Some of the new features in ipv6 have already been tried in other
protocols... protocols that ipv4 has already replaced in the market.
They won't be the adoption drivers people seem to think they are.  v4
may not be as efficient as v6, but it is efficient enough, and until
it cannot handle the apps the mainstream users need, the mainstream
won't use it.

Fortunately, unlike VHS vs Betamax, you can quietly include support
for both in a single device with no or little excess cost, and, like
cassettes vs CDs, you will be able to have one mass market for the
good enough right now, and one smaller market for the -philes, and
slowly shift from one to the other.  First, though, you have to make
ipv6 perform.  ipv4 has been worked on by some very competent people
for a long time; to pull out yet another comparison, like rotary vs
piston engines, even if ipv6 is theoretically better than v4, the
implementation and support have to catch up before the wide deployment
can really get started.
