Just now i called up asus customer services to ask them where have stock for n56vz i7. They said whole malaysia no stock already, and there should be new n series replacement. Then he told me "From what i heard, the new n series should reach malaysia around may". He even ask me to check asus facebook page for latest news. I think the new n series replacement model should be N56VB with gt740 rather than gt650.

PS: i'm currently looking for n56 model also. But very hard to find.
