Perhaps on the business/marketing side...
...I wondering whether being part of a larger group has killed the boutique image and thinking. Remember thinking Cervelos were more of a premium brand. Half price discounts certainly kills that image!
From everything I looked at regarding Cervelo and the acquisition by Pon, they (Cervelo) seem to be in a much better position than they have been in most recent years. If anything, they're far stronger. It's to be expected that some changes will be made with an acquisition like that, but the core Cervelo group is still the same that it's always been (although Vroomen is doing his own thing with mountain bikes now).
It seems to me that the 50% off of 2012 frames is nothing more than an end of year/end of paint scheme clearing of those items from inventory. That's why it's such a great deal. To suggest that Cervelo is slipping because of this is just silly.
Nytro, a premium Cervelo dealer here in Southern California, have started listing the 2013 models along with 2013 prices on their site. There's nothing cheap or discount about those prices.
