I will second that opinion!
Just look at what happened to Penang after the last election for reference.
I do think the rate of development in Iskandar Johor will go into higher gear almost immediately. They will ride the Iskandar project and maximise political brownie points. What better still when the foundations are already laid out on a nice (probably not silver) plate by the previous administation for you?
FDI is a sizable contributor to the GDP. It is in nobody's interests to do a about-turn and dampen the FDI environment. It is a cash cow. There is evidence of a global manufacturing glut and excess capacities. The recessionary conditions of the western economies are just going to add more downside pressure to manufacturing. Since you can't export your way to prosperity, FDI becomes even more important in the growth game.
Already since 2008, there has been intense competition at the state level as to who is drawing the most FDI into Malaysia. Penang has been beating their chest about their contribution to FDI hence growth of Malaysia. Obviously Iskandar Johor is not to be kept down. They also have been patting themselves on their backs to Putrajaya too.
Raising the floor limit to 1 mil RM for foreigners to buy properties in Johor is almost a given. Not if, but a matter of when. The "when" might come sooner than you think. It will be politically expedient for the incumbent to show its voters something has been done to address the escalation of housing prices. No doubt the lines between the two tier market will be much more evident. The local market and the foreigner market. There potentially might be a huge price distortion within the foreigner market itself.
We just need to bear in mind while all this is hunky dory, one must not forget the faster this booms, the faster the lines of social and income inequality comes up clearer. As long as there is a broad based growth in the country I guess it is ok.
