The invitation features a pair of denim jeans and the caption "1000 songs in your pocket changed everything. Here we go again."
The iPod line has been continually refreshed year over year since introduction and continues to be a possible candidate for this meeting. However, speculation from AppleInsider points to the possible release of the iTunes-capable Motorola phone that has been rumored for months.
[Update] According to the Wall Street Journal, Cingular will be the carrier to first offer the iTunes-capable phone, having reached an agreement with Apple.
