GB is waiting for DRV's SP to bounce (MMI holds quite a bit of DRV's shares). Until that happens, MMI won't be listed.
Speculation of DRV's SP moving higher in the short term is probably well founded IMHO; I guess we'll see. MMI is basically broke without it's DRV shares being worth more than 11 cents.
I'm simplifing things of course, but I believe that's it in a nut shell.
