What location and resorts are you looking at. Many II members don't deposit until a few months out as there is currently no incentive to deposit early though that is supposed to change in a month or so. If you're waiting for air fare, that might be a problem. Caribbean owners tend to be particularly late, 2-3 months before the travel isn't uncommon. HI can be almost as bad, other than maybe Kona Coast Resort. They can't get you anything that other II members haven't given to them.
11 months out is still very early. I wouldn't get antsy until around 5-6 months out. If there's a reason this would be unacceptable, better make a back up plan and then modify your request if needed. Many times making a hotel or condo reservation, sheduling air fare then searching for the same thing and cancelling if you match can be a good strategy.
