This is an interesting question.
In talking to your vendors with your checklist of capabilities a device CAN/SHOULD/MUST have, what if you no longer needed to carry 350k/512k routes of IPv4 and only needed 256k of IPv6 ?
Instead of 6pe think of 4pe with ipv6 core.
I've been reminding vendors that IPv6 should get new features *first* vs IPv4. The end of IPv4 is near, but that doesn't mean the end of the Internet is here. The next chapter gets a new page turned. Maybe we will determine that IPv6 needs to go the way of IPX/Decnet/AppleTalk and some new system (non-IP even) will take over the world.
Either way, it's an interesting time to be an edge operator that worries about CPE stuff. those that think mostly about core this is a big fat *yawn* imho. Expect application developers to face some interesting challenges. me? I'm waiting until I see the "NOW WITH IPv6" sticker on things at the store.
