Not unless they decide to completely revamp how addresses are assigned, no.

Edit: and to address the comment that slipped in just ahead of me...MAC addresses as a part of IPv6 addresses are fine. If the interface is on several subnets, then the network portion of the IP address will be different.

Edit2: To clarify my initial comment, as the other commenter stated, there is no effective way to handle the routing for keeping the network portion the same, so that would always depend upon where you are. The only possibility could be to be assigned a permanent host ID, but considering how many devices the average person has with network access (I have a couple dozen easily, but I'm not average,) I'd think that this would be impractical anyway.
