Sometime beyond 2050
Never - its not humanly possible
I agree that a lighter boot is necessary- but it cannot be a less supportive boot. Heavy materials aren't necessarily better than light ones- it is all about the technology used. It is possible the technology to make fully supportive light weight boots for quad axels doesn't exist yet.The consensus among skaters and coaches (Stojko, Mishin) is that someone would have to develop a lighter skate with enough support.
It will be done by Max Aaron, in January 2015.
Artificially reduced gravity?
Ice rinks with some springy surface beneath the ice, or specially formulated ice that has springy properties of its own?
Unlikely to become standard in all training rinks everywhere, considering that figure skating rarely pays the bills for standard ice rinks and hockey/public skating (nor speedskating or curling, which don't pay the bills either) wouldn't need the spring (or the lower gravity).
I wonder if Yuzuru Hanyu could?
It will be done, and the skater who does it will receive positive GoE for licking his elbow in midair.
I think, it's possible.
Tonya Harding did a clean Quad Loop in practice back in 1991. Unfortunately there is no known footage of this.
I think it is possible. The key is a field of talent. If figure skating gets really popular and a LOT of children, as many as baseball or football, engage competitive figure skating, I think it will happen pretty soon.
I think off-ice weight training will be the key here. Mao, as of 2010, was said to be performing barbell back squats with 50 kilos. If, over time, she could up that to 100 kilos, who knows what she'd be capable of in terms of jumping. (Kristi Yamaguchi did squats with 102.5 kilos in preparation for the 1992 Olympics, so this is obviously possible.)
Heavy back squats, then, together with explosive exercises like power cleans and power snatches, and perhaps some plymometric jumping, would certainly increase any skater's vertical jump height, and time in the air.
So, for the 4A, if one day a female skater builds up to a single 140-150 kilo squat, and a male skater up to a single 180-190 kilo squat, then the jump might be cleanly landed.

For the 4a, I think a lot f things are possible - both the talent pool, equipment, modern training methods are essential. Look at a guy like Usian Bolt or Micheal Phelps, who are so extraordinary in their fields.
I wonder if the talent pool will not be the real limiting factor - but what could a Dick Button have done with today's boots and training methods?
