I got some information about an upcoming Nikon D5000 rebate in Australia (valid: June 15 - July 30, 2009):
D5000 Body Only : A$ 100
D5000 + any AFS lens: A$ 150
D5000 + 18-55VR +55-200VR: A$ 200
Nikon D5000 was released less than two months ago.
There is also a report that the Nikon D5000, D3 and D3x prices were reduced in Canada at the beginning of this month:
Nikon D5000 + 18-55VR +55-200VR for C$ 999 (C$ 60 less than the original price)
Nikon D3 and Nikon D3x: C$ 250 rebate
