New RM50 denomination, Commemorative or for circulation?

I think there is a wrong statement by Bank negara about this banknote. You can read the full Bank Negara Press statement here: Bank Negara statement 21 december 2007.

Bank Negara said that "This new design of RM50 banknote is the first denomination of the Fourth Series of Malaysian currency notes which will be replacing the existing series in stages" and "The new RM50 banknotes without special packaging will be available through commercial banks on 30 January 2008 onwards". Today is 7 October 2008, I went to bank to change money for Hari raya aidilfitri celebration and asked for this money, they said RM50 denomination still using the old design. This design only for sale? 50 million pieces of this item suppose to be circulated in their statement. over 10 month and none of it available?

Bank Negara Statement also told us that this banknote is to commemorate Malaysia's 50th Anniversary of Independence. Is this a commemorative RM50 banknotes or banknote for circulation? Bank Negara Malaysia please make your statement a bit clear.
