Alex, Since 6to4 is a transition mechanism it has no long term future *by definition*. Even if someone chooses to design a v2, who is going to implement it? If you have a reason to install and enable 6to4, why would the nominal status of a couple of RFCs make you do anything different? Of course, if implementors choose to drop the code you might not be able to upgrade software versions - but hopefully by that time you will have native IPv6 service anyway.
