I think Powerbook G5 or certainly a dual core G4 by next year.
A bigger capacity iPod. But the with iPod mini leading the way in miniaturisation then the iPod senior may have an identity crisis.
An iPod Mini gives the average jogger, on the road person as much music as they need with a few gigs.
This leaves the door open for an iPod with?? Bigger hard drives, a colour screen for viewing Photos on? Controlling a digital hub device? Steve Jobs says no confusion. It's the music stupid.
So we're left with small and big/small for the iPod range.
Instead, I more likely see an xPod that will bring the video/digital hub pod we're after. An iPhoto/iDVD device that will test movie clips/footage...for pros on the go and view/store photos. It still won't be big enough to edit iMovies on. heh. It will be a viewing device. A screen big enough to see iCal diaries in colour.
A PDA or a PLD Personal Lifestyle Device. They could even hook in some phone capability. I could gig talking to a videoPod brick.
A bit of Newton capability in there.
Knowing Apple. It's going to be a different device that builds on the Apple 'cool' and the iPod brand. I see this expansion more and more for Apple in the coming years.
But they've got to get the next DLD dead right. Or they'll kill their Apple into Consumer Electronics momentum.
PowerMacs. Dual Core next year. Otherwise we could be well behind an Intel equivalent.
iMac. G5 by next year.
iBook. 2 gig G4 by next year.
eMac. G5 by next year.
'X' on 10.5 next year.

X-Serve on 3 gig by next year.
Will we see Apple advertise next year?
Nope.
