So moving back to the point here.
On average, HK versions will "officially" be 3-6$ less than US prices, *1 and may or may not be region locked
On average, HK versions will "officially" be 5-15$ less than US RRP *2
On average, CN versions will "officially" be 5-10$ less than US prices, but be region locked
On average, CN versions will "officially" be 5-20$ less than US RRP *2
However, "officially" does not in any way garuntee that they will retain that pricing, and there is nothing stopping stores from increasing the prices.
*1 No solid confirmation given to state yes or no, however so long as the hardware and software are not bound by the same laws as mainland china around requirements to sell, it should be region free, we'll find out for sure soon enough
*2 US RRP remains artificially high on major chain stores such as bestbuy and gamestop, but most online only retailers offer the same titles with up to a $5-$25 discount)
