OK folks, the invites from Apple’s PR team were sent out today. The essential text reads:

1000 songs in your pocket changed everything. Here we go again.

So you can bet that between now and that day, the rumor sites are going to be on overdrive, trying to second-guess His Jobsness and figure out what the big surprise is going to be.

People will doubtless be placing money on some kind of video device, a videopod that does for film and TV what the iPod did for music. That would be the kind of thing to ‘change everything’ again, wouldn’t it? Especially if it had some kind of direct link to an iTunes Music Store-style service for the downloading and purchasing of video content.

What other ideas could change everything again? An iTunes phone, or combination phone and iPod device, might be interesting, especially if it could connect directly to the iTunes Music Store and download songs without the need for a computer.

Or might we see a radically different handheld device, one that’s more like a computer than a player of files? Something that runs OS X and can be used for all manner of mobile computing functions, music and video included.

I’m inclined to suspect it’ll be some kind of video tablet device. But heaven forbid I should ever indulge in groundless speculation. That’s not like me at all.

Sooooo, whaddya think it’ll be, huh?
