I'm going with the assumption that GM will price it out as per the competition, especially if they want to steal potential purchases from the competition.
2010 Camaro 2SS/RS = $35,380 US
2009 Mustang GT California special edition with all the goodies:
Cdn = $36,000 ( after $5000 rebate )
US = $34,000
2009 Challenger R/T
Cdn = $38,855
US = $36,500
