So I guess the best assumption is that they may flash the ECU for the 2013 model year and the 2012 cars may get the upgrade for free. As andy says, that would be a very nice reward for early adopters, so I hope it comes true. Also, it would mean anybody picking up a lightly used 2012 right now will be getting a hell of a deal as their car may be upgraded to the new power spec in conjunction with the price increase.
The next obvious question is how much of a power bump? I don't want to have unrealistic expectations (and then get let down), but it would have to be at least 15hp to even be felt, no? Plus no loss of torque? On the other hand, can't be more than 30hp, I would think, or else they won't leave enough headroom for a 12C GT3 variant? I don't want to wind anybody up (we don't need another TAG!

), but I'm really wondering what a realistic number would be.
