I wouldn't anticipate them restocking an older model when the newer one is released as it'll cannibalise sales. And they know that users will prefer the A52s over their newer A53 for chipset reasons alone.
You're better off sourcing elsewhere. Besides, their $120-off pricing should be similar to street pricing, with some forumers here sharing they got their sets at $3xx after discounts, or even $400ish without discounts.
