Though he doesn't spill where he got the information, author Thom Hogan is usually a relatively reputable source of Nikon
leaks rumors. The latest whisperings to come out of his mill are about the replacement for the D80. Although he mentions that Nikon's first quarter financial meeting is this week, he doesn't explicitly draw the cynical connection that my brain's making about the timing of this information.
But anyway...he claims the D90 will have a 12-megapixel sensor, shoot about 4.5 frames per second, and have a Live View mode that shoots video. Cool, if it's true. Plus a new kit lens--the 18-105mm f/3.5-5.6G DX VR.
