Might want to double check you aren't filtering, as parts of 1/8 and 2/8
have been intermittently announced by RIR's in debogonizing efforts over
the last few months.  Routing wise, this really isn't different from the
space being assigned - better to clear up any filtering and identify
routing problems or renumbering efforts you may need now before the
space gets allocated, probably later this year. 

In fact, parts of 2/8 are being announced right now for debogon-izing:

When do you think that 1/8, 2/8 and 50/8 will start showing up as live,
assigned addresses.

I don't see any of them coming in on my core routers yet.

We allocate RIRs approximately one /8 per month. So you'd have to
reclaim 12 /8s to extend the allocation pool by one year.
