Amount of cabins available for a cruise

[chrismakris]

We are about 10 months out from a cruise to Australia on the Eclipse. 
 

 I decided to do a check as to cabin availability on our ship and I couldn’t help notice there are still almost 700 cabins still available. 
 

I understand that Australia is a long way to go for the majority of people who cruise and that this is the last cruise prior to Christmas (it finishes Dec 23) so I’m just wondering if this is a normal amount of cabins to be available or should I be on the lookout for a price drop soon?
