The "tipsters" consulted by the site say the announcements could come as soon as March, and that topping the bill will be a black iMac.
MacScoop also says the XServe series, MacPros and Mac minis could be in line for a spruce-up as they have served the longest time since they were last refreshed.
A black iMac would make sense; it's the machine designed to appeal most to iPod purchasers who fancy a bit more Apple kudos. iPods and iPod nanos have been available in black for some time, of course.
The reports would tie-in with the rumoured March or April appearance of Mac OS X Leopard, Apple's latest operating system.
