Defrosting meat - broken freezer
You should be fine for 10 hours if the freezer was working fine (at the proper temperature) at the beginning of that 10 hour period. If you are past 10 hours when the new freezer is ready, you're still very unlikely to be over refrigeration temperatures.  

Starting NOW, don't open the freezer until you're ready to transfer the food. If everything is still frozen when you go to transfer it, you're golden. If it's cold but has just started to thaw, you're still OK as far as for safety to just refreeze, but you may see some loss of quality. If your stuff is still cold to the touch but partially defrosted, pick the most expensive meat to cook that day, the rest of it is likely to face some quality issues if refrozen. If it's not cold anymore, consider it a lost cause, safety cannot be guaranteed.

Unopened vegetables aren't really a safety issue, but they might take a quality hit.
