On a side note, since HDB prices new flats to existing
surrounding resale flat prices, it means that this DBSS could be a
reference point for pricing of new HDB flats around the area in the
future.
So people are actually justified in questioning the high price
of this project.
Today, the DBSS flat costs 880K.
5 years later, it sells for $1.2 million.
New HDB flats around that area could be priced at say 50%
discount to this reference point - ie. $600K.(And this is a
massive 50% discount in my example) 
Mr. Khaw said on the news today, if you guys think that the flat
is expensive then don't buy, but then again, all the property is
controlled by SLA, if you don't buy where are you going to
live.
SLA sells land to private developers at market rate; SLA sells
land to HDB at private rate.
