Many of us hear stories about certain places. 
I am talking about Hong Kong.  
There is a certtainity that You can find any piece of hardware or software on that island. 
I've been there on several occasions and had no success in finding staff that is extremely popular in other places. 
I could not find English version of WiiFitPlus in Early 2010.  DjHero for XBX 360 during same period. 5 months of game release and everybody is starring surprised. 
It is almost 2 months since RockBand 3 release. No software, no instruments. 
Or maybe I was looking in wrong spots?
You can find that staff on Play-asia.com.
