Apple rumor Monday, late edition: leaked specs, model numbers, announcement tomorrow?

The flood of Apple hardware rumors just won't let up -- not only did commenters dig through those Airport Extreme and Time Capsule FCC filings and find evidence that the new models will indeed support simultaneous 5GHz and 2.4GHz operation, we've got iMac model numbers and leaked specs for Mac mini and Mac Pro, all of which are said to be arriving as soon as tomorrow. Of course, given the conservative / obvious nature of these updates, all of this information could be coming from some fanboy lair deep in a parents' basement somewhere and still sound plausible, but hey -- we'll find out soon enough, right? Here's what we know so far:

• The iMac will apparently come in an entry level MB147 20-inch model, as well as three 24-inch SKUs: MB148 "mass-market," MB149 "high-end," and MB420 "ultimate." All models will go to mini DisplayPort and feature Core 2 Duos up to 3.06GHz.
  
• The Mac mini will indeed feature five USB ports and that funky dual mini-DVI / mini DisplayPort configuration, but it's also apparently going to an NVIDIA chipset like the MacBooks and iMac. The base MB463 model will start with a 2.0GHz Core 2 Duo, and there's also a "high-end" MB464 configuration.
• The Mac Pro will come in eight-core configurations from 3.0GHz to 3.6GHz and 16-core configurations in 3.6GHz and 4.0GHz flavors, and it sounds like it's going to be even funkier on the video tip -- our tipster says it has two regular DVI ports and a mini DisplayPort. Sure, okay. It's also apparently a bit lighter than the current model, at 35 pounds instead of 42.
  
• Tipster Tom noted that the Airport Extreme and Time Capsule FCC filings contain direct references to simultaneous 5GHz and 2.4GHz operation, so that's looking even more probable.

Obviously we'll let you know if all this stuff slips out with no fanfare tomorrow, but with PMA and CeBIT both going on right now, we think that March 24 date is more likely -- Apple does like to hog the attention, after all. Anyone else have any secrets to share? We're all ears.
