We've got less than 48 hours until Apple's last Macworld keynote, and the rumor mill keeps hinting that Phil's gonna announce new Mac minis, which so far are purported to have the Macbook's NVIDIA chipset, aluminum casing, and an SATA optical drive that can be swapped out for a second HDD. Go ahead and add dual display support to that list, which is what Apple Insider is speculating based on their sources saying the new minis will sport both a mini DisplayPort and a mini DVI connector. Additionally, the site has managed to snap some shots from the Moscone Center of the expo being set up. There's a picture of a monitor showing what's presumed to be a live feed of the keynote rehearsal with a blurred figure that kind of looks like Al Gore, and inside the south hall there are several mysterious banners concealed in white cloth. So pretty much status quo, though is it just us or do the banners seem to look a little tired and thin this year?
