If you read the long description of the 2010 ZX14 you won't see any "new" features. When the 08 came out they made of point of mentioning "new" features, even if only in passing. For 2009, nothing but paint. For 2010, nothing but paint.
The first indicator this is true in the real world will be when PC5/map packages start listing as 2009-2010 with no seperate selection for 2010, meaning nothing has changed since 2008. Fuel Moto and Brock have admitted the PC5 map for a given exhaust system configuration is the same for a 2008 and a 2009, assuming no other mods.
I expect we will see the same with the 2010.... just new paint.
Given the global economy, the still-rising unemployment rate in the US (if not Kawk's largest motorcycle market, then close to it), and financial pressures on Kawk (hence, retreat from MotoGP and only token support in World Superbike), it is unlikely the ZX14 will significantly morph even for 2011.
If the company's finances improve, and the consumer economy improves, we are more likely to see a whole new line.
