Sirius Backstage has a slew of photos of the Sirius S50 next to the Delphi MyFi, and here's Orbitcast's contribution to the mix (you can also catch my own in-hand photos of the S50 here). Again, these are the floor demos but word has it that the actual S50s are on route.

Numbers ranging from 20,000 initial shipments to 300,000 and even 400,000 500,000 S50s (!!!) for the Holiday Season are flying around - still nothing additional on the delays though. As info comes in, it'll be posted so stay tuned.
