Apple to introduce host of new machines, new multitouch input devices tomorrow?

We're not sure why John Gruber and Dan Lyons are having some sort of megalomaniacal Apple super-pundit standoff, but we'll sit here and take the spoils: Gruber's just one-upped Lyons's earlier vague tease of new Apple gear tomorrow with a pretty specific list of things he's apparently heard we'll see, including new iMacs and plastic MacBooks, revved Mac Minis (including one that runs OS X Server), a new multitouch "Magic Mouse" (ha!) and some sort of multitouch desktop trackpad accessory. That pretty much covers every rumor and vague whisper we've heard over the past few months, so it's actually a fairly conservative set of predictions, outside of that trackpad -- which itself may or may not be related to this multitouch input device patent from a couple weeks ago. We'll see what happens tomorrow morning -- at this point we're half expecting a tablet, a pony, and some sort of multitouch waffle maker as well.
