You will find that all the manufactures now will only do major updates every 3-4 years due to rising costs. The r6 has pretty much stayed the same since 2006, the CBR the same. The 675 did not change for 3 years and when it did it was only minor changes. Susy changed their gsxr range nearly every year or two until now.
The current zx6, 675, gsxr600 will not change for a few years as they are all solid and amazing bikes. The CBR and R6 will have a change next year or so as they are falling behind.
