I won't be too sure about this. Not all those 2-room owners are foreigners. Once the state government will see so many empty condos in JB and the locals may start to appeal, they may provide this reprieve. Anything is possible in Malaysia. They can always revert back to the RM1m restriction at a later date when the whole economic situation will improve, although they won't tell you when.
You are extremely right on the part about "Anything is possible in Malaysia".
If you really think that local authorities, the MP and whatnots etc will actually bother, prepare to wait for maybe about 12 years.
In the meantime, watch this for some reference :
