It's funny that some people act as if they knew what Apple is going to do or not...
"There will be no wi-fi"
"There will be no touchscreen"
"There will be no Touchscreen iPods until 2008"
I mean, no one knows if any of these things are going to happen nor when they will arrive, so, it's best to start your posts with "IMO" because that's what it is, unless you're way up in Apple's hierarchy, there's no way that you're opinion is more accurate than the guy posting above or below you.
Having said that... my prediction is that the new iPod will be touchscreen, I say this because, if you follow the logical order of things you'll realize that:
People wanted a Video iPod, they got it, however, the screen is way too small to actually watch a 2 hour movie and it just feels ackward.
Ok, so, Apple needs to make the iPod screen bigger without compromising it's size and form factor. So, my guess is that a touchscreen display will be essential to the 6G iPods, not because "it's cool" or that "it's already in the iPhone", but instead because there's a need to make the screen bigger without changing the iPod size, and Apple already has the multitouch techology so, it's only a small step to implement it in iPods too.
IMO, the new iPod will also have Wi-Fi, however, I don't think it will have a web-browser like the iPhone.
I think that the Wi-Fi in the iPod will be used to make right what "t3h Zune" got wrong.
True Wi-Fi streaming of music from another iPods, imagine that you're on the train (subway, bus, whatever) and you can go and search "shared libraries" from other iPod's around you and listen to the songs (streaming, obviously)!
This would be a killer feature, and, once again, Apple already has the technology to do this, so, it's easy to get it right.
Wi-Fi doesn't necessarily mean "Web Browser and E-Mail", but it opens the doors to YouTube, Wireless Synching, Shared iPod Libraries and a whole lotta stuff we can't even imagine.
BTW - The Front Row 2 interface idea for the iPod and the "touchscreen tapping screen commands" would be perfect
