2005 Bird Definitives - 30sen 2008/1

I went to post office to buy stamps today and found the number serial for the 30sen bird definitive has reached 2008/1. I was taken aback, honestly....... I thought the bird definitive denomination for 30sen would most likely be replaced by the recently released garden flower state definitives (issued on 31 December 2007). However, the appearence of the series number 2008/1 has made the fate of the garden flower state definitives become uncertain.
