Thats funny. i never felt the type 99 was ever meant to be mass produced. It's rather expensive. The type 96 is the one the PLA has set for mass production, while the type 99 is produced in limited amounts for elite units. Since these units contain china's best tankers, why not protect them?
The design decision was probably weighed carefully. I could think of a few arguments for each side:
More crew protection side:
More survivability, leading to more experienced crews, lower replacement cost for training new crews.
Better morale.
Less expense repairing vehicle.
and more I can't think of...
Less crew protection side:
Stay with proven, mature design, and not risk a new design.
Less development costs.
The crew are pretty much goners anyway if tank is penetrated by APFSDS anyway (but not necessairly small HEAT rounds, but then, perhaps HEAT are less likely to penetrate into the hull where the rounds are stored).
May be easier to adapt current autoloader with more protections (like armor protecting the rounds? who knows).
A bustle autoloader may be a difficult problem in the engineering sense.
and more I can't think of...
I'm sure the designers weighed the pros and cons and this is the decision they chose. If you want to get inside their head, you'll have to ask them...
Oh, a side note. There's been speculation about what exactly that "box" at the back of the Type 99 and Type 96 turret does. I don't think there's ever been a photo released of the actual autoloader, leading some to speculate that it may indeed already have a bustle-mounted autoloader.
