These shift knobs respectively are:
S5 S-Tronic Shift Knob and Boot - $234.00 each (Retail - $270.00)
RS6 Automatic Shift Knob (Air Leather) - $189.50 each (Retail - $231.30)
The new S5 piece only comes with a shift boot, not sold as just a knob. Comes with grey, red or brown stitching on the shift boot.
That second knob is a standard RS6 knob with air leather.
If anyone is interested or has questions let me know.
Cheers,
