No technical reason to wait, it's just that I can't see redoing the network
today, updating all that needs updated to run MPLS, then having to go thru
that all over again to move to IPv6. I think it makes more sense to do one
upgrade and move to both at the same time, that's all.

ISP's have to consider more than just the protocol change, there are load
balancers, traffic monitors, problem alert paging systems, customer network
access, authentication systems, IDS systems, all this stuff needs to be
modified when you make a change like MPLS or IPv6 so it's better to disrupt
things once instead of twice.
