Will Iskandar become Malaysia's Shenzhen? Really?

Iskandar in Johor recently getting hot, especially after the two PMs from both countries recently launched three projects in Johor.

Everything looks beautiful when I read all the reports, but after I saw the map of it, I'm really surprised. Wow...it's three times of Singapore, and two times of Hongkong. How many people do we need to support the growth there? and where are these people come from? Immigrants? hot topic again.
