This is now a 99.99% confirmed rumor: besides the Nikon D300s and the Nikon D3000, we will also get two lenses:
AF-S DX Nikkor 18-200 f/3.5-5.6G ED VR II
AF-S Nikkor 70-200 mm f/2.8G ED VR II
Both will be improved versions of the current models.
After all, there was a reason for the 70-200mm f/2.8 rumors buld-up in the past few weeks.
