Well, other than the immenant (sp?) video ipod, a preview of leopard, new powermac cases (my guess) updated ibook form, universal pro apps, and overhaul to intel, 2006 really is the year of transition for apple. Sure they have to keep ipods fresh for christmas, but this year is taking a ton of effort to get the new chips transitioned.
As for NEW THINGS, I can see them coming, but at a slower rates. How many other types of media can you make an iTunes equivalant for? It really is perfect given the technology of today (download times etc).
I think SJ said it best in an interview after macworld 2006, 'we don't know how to make them any better' (or something very close) refering to form factors. The best example I can think of is the colors, how can you improve on the aluminum and white? I mean, white isn't exactly my cup o tea, but really, they have achieved a level of simplicity, and IMO perfection, that is hard to top, and to completely revelutionize everything again. It takes new technology to do that though, ie LCDs from CRTs, what a difference that made for the iMac.
But I'm in your boat, bring on the wow factor again.
