Correct me if I'm wrong, but if I recall correctly SC2 SEA server also died off and Blizzard moved the players over to US server, similar to how they closed the Russian server and moved the player base over to the EU one. I take that as another indicator of SC2 not doing as well as they expected here. Also, no more excuses for them to blame the price on the 'expensive bandwidth costs in Singapore'.

i heard asiasoft is in charge of distribution of D3 in this region. are they also responsible for providing this regions servers as well ?

you mean Diablo 3 can be finished playing in lets say 6 months or lesser? Its not like  WOW where people play for years?
