I was the source for this item (well, at least one of them). I was in the Towson Maryland Apple Store on Saturday and asked one of the floor people when the iPod minis would be in stock. She said "we'll have them here, available for purchase, at 6 p.m. on Friday February 20th."
She also offered to put my name on a list for a color preference with no obligation (i.e. no $ deposit). I was in a hurry, so I didn't ask her any followup questions, such as whether there would be an event at 6 p.m., how the "voting" on the colors was going, etc. Anyone who's going to be in an Apple Store soon may want to ask.
As for why I would consider the mini over an admittedly larger-capacity 3rd Gen whitePod:
1. Ergonomics. In our family, we have two of the original iPods, both with the buttons arrayed around the scrollwheel. I may just be a curmudgeon, but I don't like the button placement at all on the 3Gs. If the smaller scrollwheel with the integrated buttons feels right when I try one out, that may be what pushes me over the edge.
2. Size. These are not enormously smaller in actual size, but they "feel" a lot smaller. For the total geek experience, CDW has a printable .pdf that your can cut out and assemble to get an approximation of the mini's size.

3. Storage is really irrelevant. With smart playlists and some careful selection for a 2 gig permanent collection, I can have an effectively unlimited number of songs on any iPod. I plan to create a 500-meg playlist of recently-added tunes and a 1.5 gig playlist of songs I haven't played in the past month. With a 4,000 song iTunes library, that should keep me in "new" music for a good long time.
My only concern with this approach would be wear and tear on the drive as I sync, as I imagine this will lead to a fair amount of swapping songs in and out of the iPod. Should this be a worry?
Styling also goes into it a bit, but as my iPod spends most of its time in a pocket or my car, that doesn't matter too much. Although it would be nice if the new brushed aluminum finish is scratch and fingerprint resistant.
My plans? Go to the in-store, try out the mini and decide then and there which way to go.
