Heritage R/T information can be found on the new 2009 Brochure. You can see the brochure here:
2009 Challenger Brochure (High Rez Scan)
Page #19 is the page with the information. Per that page, two B5 Blue cars will be available.
- Challenger R/T Classic
- SRT8 Spring Special
Both will have the side-panel stripes, the R/T gets a bump to the functional hood scoops that the all SRT8s have already by default, different wheels, and blue interior accents on the seats.
Given that the SRT8 is called the "Spring Special" I'm assuming they'll be in production spring of '09, same for the R/T Classic
Bob's information on ordering/pricing being available in Nov/Dec is more than likely right on the money.
